Ava and Luke
This was one of my favorite Rock Chick books! I loved Luke AND I loved Ava. I haven't loved both the characters equally since Liam and India. And Lee was super sweet in this one when he found Ava in the basement. I am actually ~70% through Vance and Jules story when I started this one (just intending to read the first few chapters that are available online because I didn't have access to my kindle) and I couldn't put it down. I had to go home and purchase this one and kept trying to convince myself to play by the rules and go back and finish Vance and Jules...but I couldn't!
I am not sure this one needs a summary (there is not so much stuff that goes down). In short, Ava has known Luke since she was eight, she gets into some trouble, goes to Luke, changes her mind, he decides he is taking care of her troubles and the rest is the story of those troubles and Luke and Ava's story.
I still love Tex. He usually makes me laugh (although I will reiterate that his foul mouth sometimes makes me cringe with his use of GD). I love Shirleen and (unexpectedly) I loved Ren. He was such a wonderful combination of macho man/sweet guy that (if I didn't love Luke as much as I do) I might have rooted for him. I like Riley as well (not as much as Ren) but he was a good character as well.
Ava's troubles were at once less scary and more scary than the other Rock Chick's, but I loved, loved, loved it.
Now, I just have to convince myself to finish Vance and Jules before going on to Mace and Stella. I have many colleagues who rely on me for book recommendations and I have having a hard time not getting giddy when I talk about Rock Chicks (that would mean I am a bigger dork than I already am, so I gotta keep a lid on that.)
