From #1 New York Times bestselling author Jennifer A. Nielsen, this charmingly quirky coming-of-age story about a boy fighting for his freedom and a place to call home is brimming with mystery and adventure.

Jaxon Averett has had some terrifically bad luck. Because only the worst luck in the world can account for the fact that he has to live with his Uncle Clive Grimmitz, Aunt Helga, and their six kids in dead-end Walkonby, Kansas. Life with Jax's cousins isn't easy—they're all bullies, and his aunt and uncle can't even remember his name.

Which is why, on the night before his twelfth birthday, Jax sneaks over to the neighboring property, floats a raft out into the middle of the hot springs lake, and drops anchor.

Jax is now the president and sole citizen of his own micronation, the Free State of Jax.

With the help of new friends, a local lawyer, and the property owner Owen O'Keefe, Jax's micronation begins to flourish. But the Grimmitzes will do anything to get him back, and they are not above sabotage. On top of that, Jax is quickly embroiled in the mystery of Owen's missing brother—and a lost windfall of the town's money.

Investigating puts everything Jax has built at risk, and when long-buried family secrets are unearthed, he must find the courage to do what's right, even if it means losing his only chance at freedom.

New York Times bestselling author Jennifer A. Nielsen weaves an extraordinary mystery and a moving and hilariously zany story about family, forgiveness, and the courage it takes to do what's right, no matter the cost.
