In 11 Birthdays, Amanda and her best friend, Leo, stopped speaking to each other for a year. What happened when they started talking again led to the adventure of a lifetime. Now they haven't spoken for another year—and the result is even more bizarre. This time it's not just about them.

Their friend's little sister, Grace, has fallen into a strange frozen state on her tenth birthday. Amanda and Leo quickly realize that Angelina D'Angelo—the mysterious old woman behind all of the magical happenings in Willow Falls—is involved.

But Angelina never gives anyone the whole story, and it will take the help of some old friends—including Rory and Tara—to help put the pieces together. Amanda and Leo must journey into the past in a race against time. As they untangle the threads of the past and the present, they wind up traveling much further than they'd ever imagined. To their surprise, they learn that it's not just Grace they're saving.

Welcome back to Willow Falls, a town where anything is possible and there are no coincidences. But be warned . . . one you get there, you may not want to leave.
