“This page-turner offers a peek into the dark side of Silicon Valley and sheds light on issues hidden beneath the glitz of startup culture, including old-boy networks, unsustainable lifestyles, and the lure of promises that are too good to be true. A riveting cautionary tale." -Kirkus Reviews

Xia is stuck in a lonely, boring loop. Her only escapes are Wiser, an artificial intelligence app she designed to answer questions as her future self, and a mysterious online crush she knows only as ObjectPermanence.

Until one day Xia enrolls at the Foundry, an app incubator for tech prodigies in Silicon Valley, and suddenly anything is possible. Flirting with Mast, a classmate also working on AI, leads to a date. Speaking up generates a vindictive nemesis intent on publicly humiliating her. And running into Mitzy Erst, Foundry alumna and Xia’s idol, could give Xia all the answers.

And then Xia receives a shocking message from ObjectPermanence. He is at the Foundry, too. Xia is torn between Mast and ObjectPermanence—just as Mitzy pushes her towards a shiny new future. Xia doesn’t have to ask Wiser to know: The right choice could transform her into the future self of her dreams, but the wrong one could destroy her.

Yvonne Woon holds an MFA from Columbia University and is the author of the Dead Beautiful series. Originally from Massachusetts, she spent three years in Silicon Valley, where she worked as a dog walker for tech elite. Other than writing, it was the best job she’s ever had. She currently resides in Atlanta, Georgia.
