Broke English teacher Penelope Schleeman is as surprised as anyone when her feminist novel American Mermaid becomes a bestseller. Lured by the promise of a big payday, she quits teaching and moves to LA to turn the novel into an action flick with the help of some studio hacks. But as she’s pressured to change her main character from a fierce, androgynous eco-warrior to a teen sex object in a clamshell bra, strange things start to happen. Threats appear in the screenplay; siren calls lure Penelope’s co-writers into danger. Is Penelope losing her mind, or has her mermaid come to life, enacting revenge for Hollywood’s violations?
