Nick Brooks, award-winning filmmaker and acclaimed author of Promise Boys, presents the thrilling conclusion to the Ethan Fairmont trilogy in which Cheese the alien returns to Earth to warn Ethan and his friends of an impending alien invasion.

Before last summer, Ethan's life was rather uninteresting. Now, Ethan can't stop interesting things from happening . . .

After a small, six-eyed alien crash landed into his life, Ethan made a new otherworldly best friend. Now Cheese has returned to Earth, bringing his family and a warning of the Light Thieves' plans to invade. Ethan is already reeling from the kidnapping of his beloved guinea pig, Nugget, and a dangerous reality sets in after one bold Light Thief sheds its disguise to attack Ethan on his front lawn.

Ethan needs his friends now more than ever, but as he and RJ continue to clash, tensions continue to rise within the group. On top of all that, he still hasn't figured out how to deal with his feelings for Di. With an alien invasion on the horizon, and The Bureau for Weird Happenings indisposed, can Ethan and his friends work together to save Earth once and for all?

E.T. meets Stranger Things in the final chapter of this remarkable middle grade sci-fi adventure series, perfect for readers ages 8 to 12.
