When I was a kid on a cold winter's day, there was nothing I liked more than to curl up with a good book from one of my favorite series and a cup of hot chocolate. Because of the library, Scholastic book fairs, and the times my parents would finally let me buy books from Borders (R.I.P) or Barnes and Noble, I'd just have to buy one of these.
1.)
The Magic Tree House series by Mary Pope Osbourne
I adored this book series when I was about 5-9. At one point, I had every single book published at the time. These books followed Jack and Annie as they traveled through time and space (I'm pretty sure the treehouse was an early prototype of a TARDIS) to help those in need and help Morgan le Fay to become Master Librarians. I used to get them in the mail regularly because my mom always ordered them for me, and I knew that whenever I knew they were on the way, I'd just sit in front of the door. I loved learning the different science and historical facts and seeing what adventures Jack and Annie would get into next. In about 4th grade, I gave them up as being "baby" books, but I would totally love to pick them up again.
Favorite Book In Series: Tonight on the Titanic
2.) The Bailey School Kids by Marcia T. Jones and Debbie Dadey

I'm pretty sure it was because of this series that I thought one of the teachers at my elementary school was a vampire. Anyway, I loved the adventures of Liza, Melody, Eddie, and Howard. Like them, I would be totally convinced that the adult they were investigating would actually be the supernatural creature of the moment and I'd be totally surprised when they found out the truth. Yes, I was a bit of an idiot, but it didn't even cross my mind about how predictable these books were.
Favorite Book in Series: Ghosts Don't Eat Potato Chips (I legit thought this dude was a ghost. No lie. And yes, I was very gullible.)
3.) The Boxcar Children by Gertrude Chandler Warner

I mean, who hasn't heard of the Boxcar children? I remember reading the first book and being sooo concerned that these kids didn't have anywhere to live. I think this is one of the OG book series about siblings solving mysteries. The first ones I read were in fact my mom's old editions, which I thought was pretty cool. I don't think I've read ALL of them because there are just too many. I don't think I'll pick these up again because they are way too sickly sweet.
Favorite Book in Series: The Guide Dog Mystery (mostly because this is one of the only ones I remember)
4.) The Black Cat Club by Susan Sanders
These weren't the most popular books out there, but I loved this series. They were about a group of three kids (ho solved paranormal mysteries and discovered ghosts. They were some of the first really spooky books I'd ever read and the second one about the angry skateboarder ghost gave me nightmares for a super long time.
Favorite Book in Series: The Ghost Who Ate Chocolate
5.) The Magic Attic Club by Various Authors
I loved this series so much and I think I might pick up a few the next time I go the library to reminisce. This series followed a group of girls (Heather, Megan, Alison, Keisha, and Rose) who met in a neighbor's attic and were whisked away on different adventures by playing dress up. This series was so important to me because it was one of the first book series I read that featured an African American main character who actually talked about the racism she faced in every day life. Up until that point, I hadn't seen that before in a contemporary book.
Favorite Books in Series: The Secret of the Attic, Keisha the Fairy Snow Queen, Cheyenne Rose, and Alison Goes for the Gold
6.) Goosebumps and Give Yourself Goosebumps by R. L. Stine

I don't really think I need to say much about this series. Odds are if you were an avid reader in the 90s, you read at least one Goosebumps book or two. These books equally made me want to sleep with all the lights on or stay up to read more. When the Give Yourself Goosebumps books came out, I was officially hooked. I recently read some aloud to my 3rd-5th graders at my summer camp and they loved it!
Favorite Goosebumps Books in Series: A Night in Terror Tower, Deep Trouble, Night of the Living Dummy, Phantom of the Auditorium, The Ghost Next Door, and The Curse of the Mummy's Tomb
Favorite Give Yourself Goosebumps Books in Series: Escape from Camp-Run-For-Your-Life, The Curse of the Creeping Coffin, Return to Terror Tower, The Deadly Experiments of Dr. Eeek, and Into the Jaws of Doom.
7.) Choose Your Own Adventure series by Various Authors
I discovered these shortly after I discovered the Give Yourself Goosebumps books, so naturally these were my jam. I mean, how cool were these? We, the readers, got to be the star of the story. I would take these to my room and act out these crazy adventures. As I look back, some of these were definitely not for 7 year olds, but I really didn't notice at that point. I mean, you got to join Robin Hood and his Merry Men, become a martial arts master, solve a murder mystery, get involved in a shootout in the Wild West, witness various historical events, be a hostage, discover dead bodies, get kidnapped by drug smugglers, be eaten by a space vampire, and die in multiple different gruesome ways.
Yeah, these were definitely not for 7 year olds. Why were these in the kids' section of the library again?
Favorite Books In Series: The Mystery of Chimney Rock, Who Killed Harlowe Thrombey?, The Underground Railroad, Master of Judo, Gunfire at Gettysburg, U.N Adventure, Shadow of the Swastika, The Gold Medal Secret, The Mystery of Echo Lodge,Who Are You?, Terror on the Titanic, and Hostage!
8.) American Girl series by Various Authors
I really loved the American Girl series, and this and the next series on my list pretty much cemented my love of history. This was my first foray into those not-so-great events of history, but the optimism of these girls amazed me. By the way, I'm 28 and still really want an American Girl doll.
Favorite American Girls: Addy, Felicity, Josephine, Molly, Kaya, and Cecile
9.) Dear America and Royal Diaries by Various Authors
This series, along with the next one, was my absolute favorite from the time I was 8, and I honestly still love them to this day. I remember getting at least five to eight of these from my library at a time and just devoured them. These books started my obsession with historical fiction. An obsession I still have. I actually still own a few of these and refuse to give them up. I just recently found out that England, Canada, and Australia have their own version so I'm planning on reading those, too.
Favorite Book In Series: LITERALLY ALL OF THEM (except When Will This Cruel War Be Over because omg that one was boring and depressing).
10.) The Babysitters' Club by Ann M. Martin
Omg, these books were my childhood. I had at least 100 of these floating around in my house at one time, and my parents finally realized I had a book addiction. I've read almost every single book of the regular series, mysteries, super specials, and super chillers. Every day, between 5th and 6th grade, I would go home and hang out with Kristy, Mary Anne, Claudia, Stacey, Dawn, Mallory, Jessi, and Abby. Yes, I realize how unrealistic some of the plot points were such as how they've been in 8th and 6th grade for years and how they go on all these expensive vacations, but I don't really care. I don't have any anymore, but now that they're on the Kindle...I just might have to revisit this series. And I will forever stan the movie.
Favorite Books In Series: Let's be real, this series has about 100+ books in it. We'll be here for a very long time if I listed every single one.
11.) The Sweet Valley Twins by Francine Pascal

If one is not born with a twin, I think everyone at some point in time will wish they had one. I was not immune to this, especially when reading these and watching every single Mary Kate and Ashley Olsen movie ever. These books were fun, and I couldn't wait to see what hijinks Elizabeth and Jessica (mostly Jessica) got into. Before you ask, no, I didn't really like the
Sweet Valley High books that much because the twins got messy as hell, and I wanted to punch them both in the face numerous times. Unfortunately, I also recently read of these and hated it, but they'll always have a special place in my heart. Of course, I may still have to pick another one up because the one I read was one where Jessica was acting really bratty.
Favorite Books In Series: The Class Trip and The Ghost in the Graveyard
