Ever since the fateful visions about Jeffrey Johnson, Celia Cleary's prophecies have focused on smaller things like minor mishaps and everyday inconveniences. It's finally starting to feel like she has a handle on her powers...until things take a turn for the weird.

One day at school, Celia's notebook magically fills in with a single name written over and over: Patrick. She uses the family guidebook to investigate and learns that the mysterious Patrick is connected to a Doomsday Prophecy--a vision that involves a large group of people, a point of no return, and a terrible future. The target for this particular reckoning? The entire eighth grade.

Celia soon finds herself in a race against the clock to figure out which Patrick at their school is at the heart of the coming disaster. As the shifting sands of luck turn against her, she'll need Grammy's voice and the help of friends more than ever. But even with their efforts combined, can they prevent the doomsday?
