Time to wrap up our latest book giveaway contest. You were asked to recast any historical moment you think would have been cooler, better, more exciting, etc. if it had happened differently. Our winner is Pat:

"April 14, 1865. Our American Cousin is played out on the stage of Ford's Theatre. The hammer is pulled on a Philadelphia Deringer. "Sic semper tyrannis!" As the head topples from the Lincoln mannequin, the would-be assassin feels the double-barrel of a shotgun at the nape of his neck — and the peerless voice of one Jack Bauer. 'That's right, Boothy. You betrayed me too — I'm just better at it than you.'"

You've earned a copy of Lies My Teacher Told Me: Everything Your American History Textbook Got Wrong by James Loewen. I'll be in touch!

And now for our next contest, which was devised by Eric Johnson:

Anyone who's ever coached or watched peewee soccer knows that the kids aren't always interested in playing by the real rules. As Calvin & Hobbes could tell you, sometimes it's more fun to invent your own rules when you want to play outside. Take a well-known sport or game and change the rules - what twists would you add to make it more fun, more dangerous, or more exciting? Our favorite rule-change will net its author a free copy of Kick the Balls by Alan Black.

Good luck!
