1. Six of Crows (2 books)
Leigh Bardugo

The Six of Crows duology, containing Six of Crows and Crooked Kingdom, is one of my absolute favorite series. The world is clearly so well thought out because of the complexity of the different nations, magic, and customs in the Grishaverse. What I appreciated the most about these books were the characters and how they interacted with each other. They each had a unique personality and story, and as the reader, I was able to truly understand their motivations because of the different perspectives of each of the chapters. Even the characters who didn't have their own chapters were still complex and well-written. Overall, I really enjoyed reading these two books.
This series has three books: Caraval, Legendary, and Finale. This series made me realize how much I love books that just feel magical. Throughout these three books, particularly Caraval, I could just feel the magic in this world. I loved going through the book and figuring out the mysteries when the main character did. Because of the magical elements, it was difficult to predict what would happen next. I also thouroughly enjoyed the romance aspect of the series. The relationships of the two couples were throughout all three of the books and I appreciated how they impacted the plot. I also loved how the author created another book series in the same world with some of the same characters because I got to see what happened to them after the trilogy ended. This series will always be one of my favorites and so I highly recommend it.
This series is seriously one of my favorite series. For some reason, although it's fairly popular, it seems a little bit underrated to me. I've read the first two books, and the third one just came out, so I'm very excited to read it. I read these books as a little treat every night before I go to bed, because they're just so cozy and comforting for me. There are several issues and problems that Emily has to face, but the books just have an overall very warm and lighthearted feeling to them. I love Emily and the love interest's romance together, it's just so cozy. These books will always be a safe place for me.
Of course, I can not forget the Hunger Games! I mostly read these books in elementary school, but I still remember how much I loved them. They might be sci-fi, they might be fantasy, who knows- but they're going on this list.
When I got these books from the library, I didn't even really know what it was about. All I knew was that I heard about it somewhere online and that it was a Chinese fantasy novel. Little did I know was that I was about to read the first five books in a couple of weeks. I wasn't completely sure of it at first because the first novel was a bit slow, but then it picked up right away. The plot was so complex and it dove into the characters' backgrounds and emotions so well. This is a fantasy romance book, so the romance was one of the biggest parts that made me love this series so much. The relationship was somewhat slowburn and it was just so fun to read. There were so many parts that made me laugh or cry, and I really just loved reading this series.
