OK I admit it, I'm a Castle fan. Well OK I quite liked Firefly and am utterly unable to resist Stana Katic, so I bought this book, Naked Heat and I'm probably going to buy Heat Rises too. Does that make me a gullible putz? Probably. It's easy enough to read and entertaining enough. I can't say it set my world on fire or that I would recommend it to anyone not enjoying the TV show - in fact I probably wouldn't even recommend it then. But as a piece of pulp, written, presumably by a ghost writer who knocks up this sort of thing in an afternoon it is OK.
