Its fair to say this is a book I've been waiting for with a sense of urgency since I finished the first two installments. It would have been very easy for this book to fail to live up to expectations, however it soared. Although I was initially a bit concerned about the book's premise it took a relatively conventional idea (I'm not going to put any spoilers in here) and wove it into the existing narrative of the first two books, answering existing questions, and throwing up new ones.
This book is much more about Trevor than the first two, which have explored a wider character base, and it is very rewarding for that fact. It feels closer to the first few chapters of book one in style. Seeing this established character pushed into a mold which is both unwelcome to the reader, but eminently logical to the plot, almost feels like a conclusion to two books worth of uncertainty about who Trevor really is.
Its saying something that this book is a lot darker than the first two, with a lot more grit. This isnt overdone, there is a sense of proportion, and the "nasty" bits of the book fit well with Trevor's changing nature.
I devoured this book in a couple of days. My only regret is that I can't (for now) buy this in hard copy so it can take pride of place with my favourite novels.
