The fourth book in the Incorrigible Children of Ashton Place—the acclaimed and hilarious Victorian mystery series by Maryrose Wood, perfect for fans of Lemony Snicket and Trenton Lee Stewart—has a brand-new look.

Turning sixteen is a bittersweet occasion for Miss Penelope Lumley. Luckily, an invitation to speak at the annual Celebrate Alumnae Knowledge Exposition (or CAKE) at the Swanburne Academy for Poor Bright Females provides just the diversion Penelope needs.

Optoomuchstic as ever, Penelope hopes to give her CAKE talk, see some old friends, and show off the Incorrigible children to Miss Mortimer, but instead she finds her beloved school in an uproar. And when Penelope is asked by the Swanburne Academy board of trustees to demonstrate the academic progress of her three wolfish students so they can judge the true worth of a Swanburne education, the future of her alma mater—and of her job as governess to the Incorrigibles—hangs in the balance.
