New York Times bestselling series

Tensions are running high when multi-billionaire Lars Sjoburg is poisoned and demands to go home and everyone is looking to Dash Gibson to solve the case in this third and final book in the New York Times bestselling Moon Base Alpha series.

Moon Base Alpha was supposed to be an exciting place to live, but Dash didn’t expect for it to be this exciting. After solving a murder and rescuing the moon base commander, he just wants to have a calm, quiet thirteenth birthday. But of course multi-billionaire and total pain Lars Sjoburg ruins it—by being poisoned.

Now there’s a murderer loose on Moon Base Alpha again. And Dash is charged with finding out who it could have been.

Everyone has a motive, and time is running out.
