The Last Assassin by BarryEisler.

I've got all of Eisler's books signed. (Well, inscribed, actually.) Did you like TLA? The new one (<I>Requiem for an Assassin</I>) is coming out in May.

The earliest book I got signed was a paperback edition of "The Hidden Persuaders" by Vance Packard. He was visably unhappy the book wasn't a hardback edition but as I was a student (at the University of Texas) I couldn't afford the hardback. Al Capp (the author of "Li'l Abner") also appeared at the University. I wasn't thinking or I could have had him autograph one of the daily comics.

Yes! I thoroughly enjoyed The Last Assassan, I'm eager to read Requiem for An Assassin but at the same time I don't want it to be over so soon.

<I>Requiem</I> is very good, too, although I liked <I>The Last Assassin</I> more. <I>TLA</I> is either my favorite or perhaps second favorite. Depends on which day you ask me.

I don't think you have to worry, though. We'll be seeing Rain again one of these days.

Zod Wallop by William Browning Spencer. He was part of a writing group I was in.

I've got a first edition HC of "Little Scarlet" and a new paperback edition of "Devil In A Blue Dress", both signed by Walter Mosley.

I have a couple Star Trek Comics signed by Howard Pursell, that's about it.

need to add to mine:

"Here's Where I Stand" - A memoir by Jesse Helms
"Jurassic Park" - Michael Crichton
"Dear John" - Nicholas Sparks

"The Enemy At Home" and "What's So Great About America" - Dinesh D'Souza
"Unhinged" - Michelle Malkin
"Rediscovering God in America" - Newt Gingrich
"Godless" - Ann Coulter
"Give Me A Break" - John Stossel

Both of these were signed in person:
Wigfield signed by Amy Sedaris, Paul Dinello, and Stephen Colbert
Me Talk Pretty One Day signed by David Sedaris

I've got a couple but L.A. Confidential by James Ellroy is my pride and joy. He wrote "doom surrounds you aura" in it, very cool.

I’m kind of jealous of some of the books listed, Harper Lee, Michael Crichton and some others. I’ve had some books signed at signings by Bill Crider, Rick Riordan, John J. Nance, J. A. Jance, David Baldacci and others. I’ve also bought some books that were autographed. Even found a Jeffrey Archer autographed book that ended up on our side of the water.

I have Michael Chabon's The Adventures of Kavalier and Klay autographed, and I just got Jodi Picoult's The Tenth Circle autographed last night. I'm also going to a Chuck Palahniuk signing for his new book Rant next month in Boston to get my copy signed.

A Man In Full by Tom Wolfe

and that's it.

Seven Years in Tibet - Heinrich Harrer

Not sure if comic books count, but I have two early issues of Swamp Thing signed by the creator Berni Wrightson.

Chopper - Mark Brandon "Chopper" Read

The Thief Of Always signed by Clive Barker. Great book. One of my favorites.

I have quite a few in my collection... But among the ones I really cherish are signed copies of Dean Koontz' children's books that he sent when my daughter was born.

I'll have more to add to my list before month's end (have met them all before though):

Harlan Coben
Michael Connelly
John Sandford

Miss wyoming, signed by Douglas Coupeland at a book signing
Signed copy of Dogma, by Kevin Smith, bought on his Web site
