I really didn't like this one all that much. I was actually able to put it down and walk away from it.I was not thrilled with the character development in this one, there was really only two surprising things...Jane's parents are separated and her dad is seeing some bimbo, and Maura and Father Daniel Brophy finally sleep together. Yucko in my book!The overall plot wasn't that good. I was not truly scared reading about the boy's perspective, it was interesting only when it came up, but never led to anything. And then Lily constantly looking over her shoulder was a bit excessive to me. And the fact that Gerritsen tried to get on the band wagon of Dan Brown's symbology was just a let down. She needs to stick to her own guns about medical thrillers and not secret societies. I already have favorite authors that write about secret societies, Dan Brown & James Rollins, and I truly wanted Gerritsen to be my new favorite author in my new favorite category all by itself, medical thrillers. Go back to your roots! Don't do what everyone else is doing!I guess I was not all that hooked on the demon and Devil scenario that was described in this book, especially the character Anthony Sansone. I really did not like him, nor his influence over the government, Interpol, CIA, FBI, and Boston PD. It's like he trumped everyone. I did not like it nor get it. And then he starts this fighting evil club. Not what I thought it was going to be, and not who I thought would typically join this club, Dr. O'Donnell, who ends up dying and then we never have to deal with the love to hate her relationship that Gerritsen has so elaborately written for usThis one just did not do it for me. I'm going to continue on with the series, but I just thought this one fell flat for me.
