Captivating thriller with a lot of unexpected twists. The prose was very readable and the plot was fast-paced. I liked the two main characters, Nic and Jenna. The contrast between the two women provided a lot of subtle characterization that let us get to know them just by the differences in how they reacted to their sisters' deaths.  

I predicted one of the earlier twists (

Brad and Kasey's affair

) but I really liked that the author took this subplot in an unexpected direction (

Sandy's involvement

). I was totally blindsighted by the ending (

Kasey is alive and Jules's death was Nic's fault

) and I liked that the author left the ending on the darker side of morally gray.
