As far as I'm concerned, there's absolutely no better present than a gift card to a bookstore. Especially when said bookstore is also online and you get to come home from work and everything you ordered is in a giant box on your doorstep.
This is what I ordered with one of my holiday gift cards, should you be interested in my reading habits, or at least intended reading habits. I mean, I don't know if they're exactly up to Keith's discerning standards*, but they work for me:
Jonathan Strange and Mr. Norrell by Susanna Clarke
Kite Runner by Khaled Hosseini
The Best American Short Stories of 2004 edited by Lorrie Moore
Einstein Never Used Flash Cards: How Our Children Really Learn--and Why They Need to Play More and Memorize Less by Kathy Hirsh-Pasek and Roberta Michnick Golinkoff (that was clearly a copy & paste moment)
Neverwhere by Neil Gaiman
Your Own Worst Enemy: Breaking the Habit of Adult Underachievement by Ken Christian
Poisonwood Bible by Barbara Kingsolver
Too Soon Old, Too Late Smart: Thirty True Things You Need to Know Now by Gordon Livingston
*Getting to mock you in print and knowing you can't edit it out: priceless.
