If they hadn't come highly recommended from a lot of people whose opinions I trust, I wouldn't have touched a series whose lead character is, pretty much, a masochistic temple prostitute with a ten foot pole. Nonetheless, the Kushiel books are quite good. Well, I can't say for the last one of the second trilogy, as that just came out -- it's in stock at Amazon, but the street date is listed as June 12 -- in hardcover and I've been reading them in paperback (since Carey is not Lois Bujold or Steven Brust and therefore does not rate a 'buy immediately in hardcover', but few are).
