I really liked the secondary plot with Isabel and Trevor. I believe the next book is their's. I'm looking forward to reading it.Unfortunately that's the only thing I liked about the book. The actions of the characters didn't jive with their secretive professions. The hero especially acted more like a hotheaded woman than a cold assassin. I understood her being emotionally closed off, but her contradictory actions made it hard to connect with her (she's a stone-cold killer who goes undercover for months at a time, yet has nightmares where she calls out names in her sleep?).
