The found family trope is probably my favorite trope ever and this series is the best at it. The whole series made me feel extremely good about myself, and I couldn't put the book down, but this one especially. The ways the relationships develop and the characters grow. It also has one of the most healthy and consensual relationships I've ever read about, and it's crazy to think that this comes from two fucked up characters who find solace in each other. Also, it has a happy ending, but it's not what you would expect. This book had me on the floor.
