What if you could write your dreams into reality with the stroke of a pen? Sixth grade is off to a difficult start for Josephine Rose Silver. Her best friend, Violet, returns from camp with a new best friend; her parents refuse to grant her more independence; and her homeroom teacher, Ms. Kline, is full of secrets. When Ms. Kline unveils a collection of old Gothamite magazines and tells her students to build their writing skills by crafting short stories inspired by the iconic covers, J.R. discovers a peculiar power: The stories she writes come true. Soon J.R. is getting a cell phone, scoring game-winning goals, and triggering school cancellations. But it's not long before she realizes that each new story creates as many conflicts as it does solutions. And when J.R. tries to write about her fallout with Violet, all of her problems converge.
