Fun futuristic mystery thriller in detective-noir trappings, this book is surprisingly absorbing once it settles down after the first few chapters. A few silly moments may pull you out of the book, but it's usually for a deserved laugh. Twisty enough that I didn't quite work it all out before it was all laid out for me, but saw the last chapter coming from the start. Fun, and worth a sequel - there's plenty of characters in this world beyond the lead that are worth revisiting, and the Titans are a decent critique of the wealth and power divides in our society. However the characters are a bit too lightly sketched and detached from reality to be taken very seriously.
