Book excerpt: From the brilliant mind of New York Times bestselling author David Yoon comes a lightning-fast and scorchingly observant thriller about how we can save ourselves from the very real perils of a virtual world. Max, a data whiz at the social media company Wren, has gotten a firsthand glimpse of the dark side of big tech. When he questions what his company does with the data they collect, he's fired...then black-balled across Silicon Valley. With time on his hands and revenge on his mind, Max and his longtime friend (and secretly the love of his life) Akiko, decide to get even by rebooting the internet. After all, in order to fix things, sometimes you have to break them. But when Max and Akiko join forces with a reclusive tech baron, they learn that breaking things can have unintended--and catastrophic--consequences.
