My own fine novel, Long Way Back, is of course still available and makes a delightful gift. ("Vaguely Creepy"--The Times of London) (No, really! I really want that as a pull quote on the paperback.)
In addition, two of my friends have YA novels on the shelves now. Trish Cook's Overnight Sensation and Dana Reinhardt's A Brief Chapter in My Impossible Life. Buy early and often!
