Sam & Ilsas Last Hurrah

Celebrate Pride every day with the party of a lifetime—or at least the best part of high school. From the bestselling duo behind Nick & Norah’s Infinite Playlist and The Twelve Days of Dash & Lily.

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 goes right, as well…in rather surprising ways.
