Attack of the Killer Earthlings — Christine Hayes

From the author of MOTHMAN'S CURSE (Macmillan, Kirkus starred review) comes a YA fantasy of impish proportions.
***
15-year-old Shaun Ramsay cleans her uncle's movie theater in the middle of the night.

She's no fan of scrubbing bathrooms or working hideous hours, but she can cope. Motivating her best friend and co-worker Spence is tricky, but still under control.

An imp movie buff named Jim, however, was not on her agenda.

When Jim and his clan decide to make a movie of their own inside the theater -- with Shaun and Spence in starring roles -- life gets complicated. Especially since imps are known for turning perfectly good buildings into piles of rubble. Add an imp film festival, rival imp bullies, and an inconvenient crush to the mix, and Shaun may be in over her head.
