Mystery and mayhem abound in the final book in New York Times bestselling author Natalie Lloyd's middle grade series, as the Problim siblings board a pirate ship to rescue their missing Mama and baby brother from the villainous Cheesebreath.

Problim Children to the rescue! Sal and his siblings follow a trail of Toot’s toots as they sail through the barrier islands to rescue their baby brother from the evil Cheesebreath. He’s been holding Toot and Mama Problim hostage in the hopes that the Problims will lead him to their granddaddy’s treacherous treasure. But not all treasure is gold, and this one was buried long-ago for good reason.

Can the Problims find Mama, rescue their brother, and destroy the treasure before Cheesebreath and their nasty neighbor Desdemona capture them all?

Bursting with adventure, mystery, humor, and heart, the final book in Natalie Lloyd’s series is an affectionate ode to the wonders of being a weird kid in a weird family.
