As expected this installment did hurt. I know a lot of readers abhor Jake and his actions and I was none too thrilled with his violence. Though I don't condone cheating and it's depressing that he feels he can't live honestly, I still can empathize with his fears and desires. And of course, I mostly hurt for Adrien because there is nothing he can do about it.
I think most of us want this as a romance but at its core it's a mystery series. I find too that I always want more relationship development in all of the Josh Lanyon books I've read, but that is probably not the point of the main story here. I will say this - Lanyon definitely has a gift. His word choice is often genius, his observations appropos. It's like you and he are having a private joke - his references and wit quite charming and impressive. The experience is in the details with no unnecessary words wasted. One more thing - I really don't like Lisa - at all.
