Goonies meets the humor and heart of Gordon Korman in this new adventure full of nonstop action and spot-on humor from the critically acclaimed author of Float.

The McNeil family has always been professional hoaxers—tricking bystanders into believing they’re seeing legendary creatures like Bigfoot and the Loch Ness Monster.

Unlike the rest of his family, twelve-year-old Grayson hates hoaxing and wants nothing to do with the business—even when the McNeils land a huge job and must pull off four sea monster hoaxes in a week.

But when things go disastrously wrong and Dad and Gramps go missing, Grayson and his brother, Curtis, are the only people who can finish the job and save their family.
