It’s only the first day of the Frankfurt Book Fair, and already there have been three seven-figure deals announced, all for debuts by American women.

The most high-profile deal is for 25-year-old Emma Cline’s novel The Girls, a fictionalized account of the Charles Manson Family. Cline, a fiction reader at The New Yorker, signed a three-book deal with Random House following a 12-publisher auction. Film rights have also been sold to Scott Rudin. In an interview with Publishers Weekly, Cline’s agent Nick Clegg said U.K. rights have been sold, and auctions are underway in “most countries in Europe, Scandinavia, Latin America, and Asia.”

Random House also opened its cheque book for Cameroonian-American author Imbolo Mbue’s debut novel The Longings of Jende Jonga, about a West African immigrant who works as a chauffeur for a Lehman Brothers executive.

Scribner acquired U.S. rights to University of Pennsylvania associate psychology professor Angela Lee Duckworth’s Grit: Passion, Perseverance and the Science of Success. The book is based on Duckworth’s research into the major indicators of future success, and is the subject of her popular Ted Talk.
