Spoilers through book 4 (Killbox). You've been warned.
This was a tough read. I waited for a long time to start this one because of the cliffhanger ending in Killbox. I really didn't like that she didn't fully trust March to tell him what she was going to do. I want them together. I want Jax and March to have their HEA or HFN. Now, I'm not sure that's going to happen (WTF?!)
This book made me FEEL. Holy crap what a roller coaster of emotions. There's a lot going on. Jax's trial, making amends. One thing I liked was Vel and Jax's unique, different relationship with him. I learned more about Vel, he is an intriguing character. Then, one thing that irritated me was Jax's ability to blame herself for, it seemed, everything.
I didn't like that ending, but I understood it. I am looking forward to the final book, but I'd lying if I said I didn't have mixed feelings about it. I can honestly say I don't know what is going to happen.
