From Saturday Night Live legend Kate McKinnon comes the highly anticipated third book in her #1 New York Times bestselling series about mad science, three peculiar sisters, and the mysterious Millicent Quibb!

The Porch sisters are going on a trip—this time, to the beautiful almost-French city of ParisToo. Between baguettes, berets, and one very big bug—what could go wrong?

Everything, of course. You see, there’s just one problem with ParisToo:

it’s where the evil KRA is planning to execute their most dastardly plan yet! It’s up to Gertrude, Eugenia, Dee-Dee, and their dear mentor Millicent Quibb, to stop those nefarious mad scientists from taking over the world. Though coming up with a plan is easier said than done when danger—like a tree that throws coconuts, a suspicious pile of sausage, or a glaring aunt—lurks around every corner. If Millicent Quibb and the sisters Porch are going to defeat the KRA once and for all, they’ll need to uncover long buried secrets (including some that might just change everything ...) and tap into the world of mad science like they never have before.

At any and all costs, the KRA MUST! BE! STOPPED!
