Warriors is a series about cats. I'm a dog person, so I never thought I'd really get into the series. That was before I read the first book. The amazing thing about Warriors is that there are SO MANY books in the series, but the author manages to keep them interesting. There are currently 6 different series within the Warriors series, as well as Warriors Super Editions. Those are super long, awesome books telling the story of a particularly important warrior. Each series has 6 books. The math isn't hard! That's OVER 36 books. If you're looking for a series that'll keep you occupied for awhile, this one's for you. 

Genre: Fantasy, young adult

Author: Erin Hunter (a team of multiple authors including: Vicky Holmes, Cherith Baldry, Kate Cary, and Tui T. Sutherland)

Description: 

For generations, four Clans of wild cats have shared the forest according to the laws laid down by their warrior ancestors. But the ThunderClan cats are in grave danger, and the sinister ShadowClan grows stronger every day. Noble warriors are dying-- and some deaths are more mysterious than others. In the midst of this turmoil appears an ordinary house cat named Rusty . . . who may turn out to be the bravest warrior of them all. 

Don't miss: Warriors: The Broken Code: Lost Stars is the first book in a new sub-series! It's coming out in April 2019.
