I really enjoyed Ten Tiny Breaths! There are so many things that I really liked about it, and there were some things that I thought were really interesting. 
 So: Kasey. She's pretty bad-ass, and a bit on the cold side. She keeps a lot of people at a distance, and isn't the most trusting person. Generally speaking, I'm not a big of fan of characters like Kasey. But I completely understand where she's coming from and I totally warmed up to her by the end of the book. 
 Kasey had a lot of healing to do after the car accident and after living with her aunt and uncle, she decided that she and her younger sister needed to leave Michigan and live their own lives. I really liked their relationship, and that both girls tried to take care of the other. 
 Interesting Thing #1: Kacey ends up working at a bar in a strip club. Kacey seemed to have some reservations about this at first, which is understandable. I find this interesting because it wasn't seen as a bad thing at all: Kacey saw it as a temporary thing, and no one made a big deal out of it. I liked that Kacey did what she needed to do in order to take care of Livie. 
 I liked seeing Kacey's struggle with opening up and trusting people and making peace with the accident. She's made some really bad choices along the way, and that is interesting thing #2. She has A LOT of issues, which she does get help for by the end of the book, where they seem to be mostly resolved. But since this is the first book in a series, I don't think we've seen the last of her journey. Anyway, I like that she's really flawed, because it shows she makes mistakes and isn't perfect. I think that's why I'm not bothered by how tough she is. 
 But forgiveness is a super-important part of the book. While Kacey has to learn to forgive herself, she also has to forgive the guys who caused the accident that killed her best friend, her boyfriend and her parents. She does, but it takes her time, especially with a twist that I should have seen coming. I wasn't sure about her and Trent before this, and I'm really not sure about it after. I mean, I get why she felt the way she did about everything, and I get why she fought her feelings for Trent on so many different levels...but I just found something about their relationship not very believable. I also get why Trent did what he did, even though I didn't particularly like some of his actions. 
 Final Thoughts: Ten Tiny Breaths is very intense but also totally worth it! I wanted Kacey to be okay and be happy and learn to trust people. I loved that the smallest moments and steps forward were so special, and Ten Tiny Breaths was a hard book to put down. Ten Tiny Breaths gets 5 stars.
