Initially, I felt that the characters were a bit weak - there are several dialogues between Andrea and Mike where I found it difficult to work out who was saying what, as their character's voices seemed very similar - but as the story progressed this didn't matter so much, as I was drawn into the fast-paced plot. Another hit from the author of <i>Relentless</i>

A little disappointed (I prefered his other books) by this one, but still a very good read !
