A 2026 Audie Awards Finalist!

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!

It’s summertime in Antiquarium and everyone has flocked to the majestic lakeside Purple Pearl Hotel, including the nefarious group of evil mad scientists, the Krenetics Research Association. They haven’t given up on resurrecting their fearsome leader, Talon Sharktüth, 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 Kagloopy Lake. All they need to do now is find a mysterious creature called a Shrimpmaid, boil the lake (and everything in it) away, and pluck up the pearl!

But Millicent, Gertrude, Eugenia, and Dee-Dee are onto them, and they are determined to stop the KRA, even though they are now full pariahs in Antiquarium society. While Millicent and the gang work together to prevent the second coming of Talon Sharktüth, they discover more secrets than they bargained for – including where they came from, and who they truly are...

It's a mad science summer vacation they'll never forget!

Don't miss the first book in the series, The Millicent Quibb School of Etiquette for Young Ladies of Mad Science!

unbelievably delightful

As an adult that needed to mental escape the hell that is reality these days: I thoroughly enjoyed this book and the performance by the National Treasure that is Kate McKinnon made me literally laugh out loud with her zaniness.

Exquisite performance

A thousand stars!!!! Not just five. Highly recommend for everyone, not just for potential mad scientists.

Always fun to listen to Kate!

Here's hoping that she continues to have success with her writing career. They are always fun and really kooky and over the top, but I've coming to expect that from her. The audiobooks are absolute perfection - I listen while flipping through my hard copy for all of the illustrations. So many voices provided by Kate (and her sister!)

Kate McKinnon is a genius!

Love these girls and their mentor!!!! Please write faster Kate McKinnon. I must know what happens next! Wish I were a kid now! I would love these books even more!!!

Love!

Great, joyful, funny narration. Creative and squirrley story with charming characters. Can’t wait for the next one.
