Review of Six of Crows-Leigh Bardugo

I loved the Grisha Chronicles by this author, and her new book doesn't disappoint.  She goes back to the world of the Grisha and centers the story around a small gang.  This gang, led by the mysterious Kaz, needs to break out a scientist imprisoned in a very secure jail.  The story revolves around the plan and this gang of six, but it's the character development that keeps the reader engrossed.  Eventually, you hear each character's story and the more you learn, the more you care.  Spoiler alert: the ending drove me crazy because I have to wait until the next book to find out what happened.  4 Elves - Highly recommended for teens and adults
