What if your dearest friends were trapped in a world that was dying? Mehera Beatrice Crosby has one great love—and it's not following the latest health fads (like her school friend Celeste), and it's definitely not Andrew Suarez (even if he does have a ridiculous crush on her). It's Imaginalis, her favorite book series. When she learns that the long-awaited last book in the series has been canceled, Mehera is devastated—until strange events begin unfolding, and she realizes that her Imaginalian friends are counting on her to rescue them from their fading existence. Soon Mehera finds herself traveling between her world and the kingdom of Imaginalis. But what will happen when she accidentally brings the villain of the series, Pralaya, back to Earth, along with Prince Imagos and his Companions? Has Mehera doomed both worlds beyond repair, or is there a way to save Mehera's world—and Imaginalis, too? Expert storyteller J. M. DeMatteis's richly imagined fantasy is a fast-paced adventure and a testament to the power of loyal friendship, creativity, and imagination.
