Xia Chan's only escapes from her boring life are Wiser, an artificial intelligence app she designed to answer questions like her future self, and a mysterious online crush she knows only as ObjectPermanence. When she enrolls at the Foundry, an app incubator for tech prodigies in Silicon Valley, she flirts with Mast, a classmate also working on AI. But speaking up generates a vindictive nemesis intent on publicly humiliating her. Then Xia learns that ObjectPermanence is also at the Foundry, too. Torn between the two, she knows the right choice could transform her into the future self of her dreams, but the wrong one could destroy her.
