In this fourth and second-to-last book in the series, Cass and Max-Ernest set out on separate, yet equally dangerous, adventures.
Cass finds herself alone and disoriented, a stranger in a dream-like, medieval world. With the help of a long-lost relative, she begins to uncover clues and secrets—piecing together her family's history as she fights her way back to the present world.
Meanwhile, back home, Cass is at the hospital in a deep coma. Max-Ernest knows she ate Time Travel Chocolate—and he's determined to find a cure. Can our expert hypochondriac diagnose Cass's condition before it's too late? And will he have what it takes to save the survivalist?
