In 2041 on Moon Base Alpha, thirteen-year-old Dash must solve the mystery of how Lars was poisoned before the base loses oxygen, forcing the colonists to return to Earth.
Moon Base Alpha was supposed to be an exciting place to live, but Dashiell Gibson didn't expect for it to be this exciting. He's already had to solve a murder and locate a missing moonbase commander. Now he just wants to have a calm, quiet thirteenth birthday. But of course trillionaire (and total pain) Lars Sjoberg ruins it - by being poisoned. Now there's another potential killer loose on Moon Base Alpha, and Dash is forced to identify the most likely suspects. Suddenly Dash finds himself with a taret on his back. Whoever poisoned Lars will stop at nothing to keep his - or her - identity a secret.
