With a mysterious Shrimpmaid and secrets of their origins at stake, can they prevent disaster and uncover the truth about themselves? Dive into a summer adventure where the stakes are as deep as Lake Kagloopy.

From the publisher

A New York Times bestseller! From Saturday Night Live legend Kate McKinnon comes the highly anticipated second book in her #1 New York Times bestselling series about mad science, three peculiar sisters, and the mysterious Millicent Quibb! The Porch Sisters are in trouble. It’s summertime in Antiquarium, and everyone has flocked to the majestic lakeside Purple Pearl Hotel, including the Krenetics Research Association, a nefarious group of mad scientists. They haven’t given up on resurrecting their fearsome leader, Talon Sharktūth, and now they’re hot on the trail of the legendary Purple Pearl, a source of power that is rumored to be lost at the bottom of Lake Kagloopy. But Gertrude, Eugenia, and Dee-Dee are on to them, plus their mentor, Millicent Quibb, has a plan! Is it a good plan? Hard to say! But it does involve finding a mysterious creature called a Shrimpmaid, boiling the lake (and everything inside it), and retrieving the pearl before the KRA gets its evil hands on it! While Millicent and the gang work together to prevent the second coming of Talon Sharktūth, the sisters discover more secrets than they bargained for–including where they came from and who they truly are… This is one mad-science summer vacation they’ll never forget!
