I can't say that I'm familiar with the Winston Breen books, but I have heard that the character/author will be placing puzzles at seven blogs over seven days starting on April 16th. Readers can solve the puzzles and submit the answers to the appropriate address (Check that link I just gave you for appropriateness.) each day to be elgible to win a copy of the new Winston Breen book, The Potato Chip Puzzles.
Here's the twist to this contest: The winners of the last day's puzzle will be eligible for a drawing to choose the winner of the grand prize, "Every single book in G.P. Putnam's Sons Spring 2009 childrens' and young adult catalog plus advance reading copies of numerous Fall 2009 books!"
That's a sweet deal.
