The Cahill family has a secret. For five hundred years, they have guarded the 39 Clues – thirty-nine ingredients in a serum that transforms whomever takes it into the most powerful person on earth. If the serum got into the wrong hands, the disaster would rock the world. So certain Cahills have always made it their mission to keep the serum safe, buried, locked away. Until now. Thirteen-year-old Dan Cahill and his older sister, Amy, are the latest guardians of the Clues. They think they’ve done everything right, but a tiny mistake leads to catastrophe. The serum is missing and Dan and Amy have to get it back and stop who stole it . . . before it’s game over. For everyone.

Here are some things about me. I live in an extremely Brazilian section of an extremely Greek neighborhood—Astoria, Queens, which is just to the right of Manhattan. (That's as you face Manhattan. If you were, say, lying on your back in the middle of Central Park with your head in a northerly position, we would be to your left) I live there with my wife who has a blog and our two cats who do not. One day I hope to have a very large dog that I can name Jerry Lee Lewis. I used to write plays (I actually have an MFA in it, which is currently number 8 on US News and World Report's annual list of the top twenty most useless masters degrees) and now I write books for teens. I've written two. One was about a girl who wanted to be a rock star and could graciously be called a learning experience. The second, is The Eleventh Plague and it comes out Sept. 1, a fact I still find pretty amazing.
