As the Great Leaf descends to signal the start of a new year, Rupert Dullz has only one wish—that the new girl in his class, Rainn-with-two-Ns Evertree will like him as much as he likes her. And then everything freezes. Literally. Only Rupert's Imagining power allows him to break free. Only Rainn is able to do the same, and as he embarks on yet another amazing adventure he'll have her very special company to help him solve the mystery.

Someone has stolen the last second of the year, locking the entire town of Graysland into a frozen moment of time. Worse, Epoch intends to throw that second into the Pit of December to ensure it stays frozen forever. Who is Epoch, and why does he hate the town so much? As Rainn and Rupert travel through the Twelve Houses of Annum on a zodiacal quest to save their home and families, finding the answers to those questions may be the most important of all.
