Natalie Collins hasn’t heard from her sister in more than half a year.

The last time they spoke, Kit was slogging from mundane workdays to obligatory happy hours to crying in the shower about their dead mother. She told Natalie she was sure there was something more out there. 

And then she found Wisewood.

On a private island off the coast of Maine, Wisewood’s guests commit to six-month stays. During this time, they’re prohibited from contact with the rest of the world—no Internet, no phones, no exceptions. But the rules are for a good reason: to keep guests focused on achieving true fearlessness so they can become their Maximized Selves. Natalie thinks it’s a bad idea, but Kit has had enough of her sister’s cynicism and voluntarily disappears off the grid.
 
Six months later Natalie receives a menacing e-mail from a Wisewood account threatening to reveal the secret she’s been keeping from Kit. Panicked, Natalie hurries north to come clean to her sister and bring her home. But she’s about to learn that Wisewood won’t let either of them go without a fight.
