The New York Times Bestselling duo behind Nick & Norah´s Infinite Playlist and The Twelve Days of Dash & Lily return with twins out to throw the party of a lifetime--or at least the best party of high school!

Siblings Sam and Ilsa Kehlmann have spent most of their high school years throwing parties for their friends--and now they´ve prepared their final blowout, just before graduation.

The rules are simple: each twin gets to invite three guests, and the other twin doesn´t know who´s coming until the partiers show up at the door. With Sam and Ilsa, the sibling revelry is always tempered with a large dose of sibling rivalry, and tonight is no exception.

One night. One apartment. Eight people. What could possibly go wrong? Oh, we all know the answer is plenty. But plenty also goes right, as well...in rather surprising ways.

Rachel Cohn is the author of critically acclaimed YA novels Very LeFreak, You Know Where to Find Me, Cupcake, Shrimp, Gingerbread, and Beta. A graduate of Barnard College, she lives and writes in Los Angeles.

When not writing during spare hours on weekends, David Levithan is editorial director at Scholastic and the founding editor of the PUSH imprint, which is devoted to finding new voices and new authors in teen literature. His acclaimed novels Boy Meets Boy and The Realm of Possibility started as stories he wrote for his friends for Valentine´s Day (something he´s done for the past 22 years and counting) that turned themselves into teen novels. He´s often asked if the book is a work of fantasy or a work of reality, and the answer is right down the middle-it´s about where we´re going, and where we should be.
