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.
