Life for Zack McGee has been no picnic since Amp crash-landed his spaceship through Zach's bedroom window. But when Amp discovers an unused telescope, he makes a huge discovery. The Erdian alien invasion is in progress.

Now it’s up to Zack, Amp, and Olivia to take action. But this is no school science fair. It’ll take more than a little gadgetry and a few white lies to get Amp out of trouble and save the Earth from an epic invasion!

Like every book in the Alien in My Pocket series, Telescope Troubles mixes Common Core–aligned science and safe, hands-on experiments with hilarious stories that young readers will love.
