There's nothing hijabi alien hunter Abyan wants more than to graduate from Carlisle Academy and finally rid the Earth of aliens, the Nosaru.

Everything is going to plan until the Nosaru kill one of Abyan's squad mates. To make matters worse, the school admins replace her elite squad member with a sub-par new recruit, Artemis. Despite Artemis failing every test--and bringing the team down with her--their cutthroat instructors refuse to kick her out.

Together Abyan, Artemis and the rest of the team unravel the mystery of why Artemis is actually there, what the Nosaru really want, and what Carlisle Academy has been hiding from them all.
