Jon:
You know the scenario; Trapped on a desert island and you can only have 10 books, magic or otherwise....

Seth,

Sorry for the delay in coming up with a list. It's not an easy task. However, here's my list:

The Books of Wonder by Tommy Wonder (So many great ideas and routines along with thought provoking essays)
Strong Magic by Darwin Ortiz (I lost my copy before I had a chance to read much of it)
The Workers Series by Michael Close (Just brilliant!)
Greater Magic by Hilliard (I’d finally get time to wade through it)
Expert Card Technique by Hugard & Braue (Back to basics and a chance to learn some sleights I don’t use)
The Collected Almanac by Richard Kaufman (So much great material from a plethora of outstanding magicians)
A Whack on the Side of the Head by Roger von Oech (A really thought provoking book on creativity)
The Magic of M.C. Escher (I love Escher’s work. I think he, like Dali, teetered along the thin line between genius and madman. How anyone can conceive of some of his images is beyond me)
Any of the Dirk Pitt books by Clive Cussler I haven’t read (I have read a number of his books and really enjoy his writing style. He also puts himself into the book as a minor character that helps the hero. A nice touch.
The Far Side Calendar by Gary Larsen (365 Far side cartoons! It would also help me know what date is while I’m stranded

I know some of those were multiple books but it's my island I can can sneak as many extra books as I like!

Excellent choices! A lot of my selections are on your list as well. I would also include a copy of 101 Ways to Build a Raft.
