If you're looking for a perfect stocking stuffer, Jo Graham's first novel, Black Ships, is out in paperback.
I've raved about Jo's books before, and will continue to do so - wait till you see Stealing Fire! Black Ships is a retelling of the Aeneid from the point of view of Gull, priestess to the Lady of the Dead, who becomes Aeneas's Sybil. It's an astonishing reimagining of Virgil - her version of Dido is both chilling and heartbreaking - and the characters are unforgettable. I actually got up at 7AM on the Sunday of a convention so I could sneak down to the hotel lobby and finish the book.
So if you have fans of historical fiction or the classics on your holiday list, or if you're just looking for a different kind of fantasy, this is the book for you. And it's in mass market paper!
