If you're looking for the perfect moderately priced Christmas gift, I'd suggest the recently released deluxe edition of The Last Unicorn. Published by ROC, this edition includes the definitive text of Peter S. Beagle's classic novel, his Hugo and Nebula Award-winning novella sequel (coda?) "Two Hearts," introductions to both works, an interview with Beagle, and more. However, the kicker is that Barnes and Noble is carrying a specially priced version of the deluxe edition priced at only $9.95. I purchased a copy today and it is an extremely nice hardback with dust cover. For the life of me, I can't tell the difference between this version and the deluxe edition that sells for $29.95 or more at other bookstores (if you can even find a copy).
Anyone needing a bigger Peter S. Beagle fix would do well to check out his story "We Never Talk About My Brother" from issue 5 of Orson Scott Card's Intergalactic Medicine Show. The issue also features a very good interview with Beagle by IGMS editor Edmund R. Schubert.
