Secret Society Girl series

Source:^[3]

Peterfreund's first book, Secret Society Girl: An Ivy League Novel, details the second semester of Amy "Bugaboo" Haskell's junior year at Eli University, a thinly veiled Yale University clone, after she is tapped for Rose & Grave, a secret society that opens its ranks to women for the first time. Peterfreund used her time at Yale as the basis for Amy's Eli experience.^[2] The New York Observer described the book as "witty and endearing",^[4] and Booklist described the book as "frivolous but fun to read".^[5] Three other books were released in the series, chronicling Amy's senior year.

In Under the Rose, Amy uncovers scandals that could undermine the very foundation of Rose & Grave: a fellow "Diggirl" seems to be feeding confidential information to a nonmember to bring the society down from within and several current and former male Diggers have formed an "old boys' club" offshoot of Rose & Grave.

Eager to escape the wrath of a rival society on campus, Amy and the Knights are whisked off to Rose & Grave's private island off the coast of Florida in Rites of Spring (Break). In addition to dealing with a disgraced patriarch in hiding on the island after the fallout from society-related scandals, Amy and her friends fall victim to increasingly serious accidents—while Amy gets close to the patriarch who betrayed her.

Back on campus for Tap & Gown, Amy readies for graduation between juggling unfulfilled gen-ed credits and helping to select a new tap class, amidst dwindling post-graduation prospects. Troubling phone calls only add to Amy's stress when her prospective tap has gaps in her resume—and a mysterious past that includes Amy's new boyfriend.

Morning Glory

Morning Glory is a novelization of the 2010 motion picture Morning Glory, written by Aline Brosh McKenna and starring Harrison Ford, Rachel McAdams and Diane Keaton. Going into the project, Peterfreund wrote, "My goal was always to remain as true to the script as possible, and to preserve the content, tone, and intent of the screenwriter." ^[6] As McKenna had previously adapted Lauren Weisberger's The Devil Wears Prada, Peterfreund "tried to think of how she'd translated the book into her medium, but backwards."

Killer Unicorns Series

Peterfreund has written two full-length novels and three short stories about or dealing with killer unicorns. These are Rampant, Ascendant, Errant in Kiss Me Deadly: 13 Tales of Paranormal Lore, The Care and Feeding of Your Baby Killer Unicorn in Zombies vs. Unicorns, and On a Field, Sable in Eternal Spring. Errant, The Care and Feeding of Your Baby Killer Unicorn, and On a Field, Sable are all stand-alone stories in the Killer Unicorn universe, while Rampant and Ascendant are meant to be read in that order.^[7]
