Dark Matter (The Starfire Wars Book 2) / Jenetta Penner

Arcadia was supposed to be Earth 2.0—a haven for humanity while they fought desperately to save their dying homeworld.

But nothing has turned out like Cassiopeia Foster had thought.

Another race, the Alku, already occupies the planet in a parallel dimension called Paxon. They are willing to help Earth, but a powerful contingent plans to strip-mine the strangely powerful Starfire from the planet, which will collapse the Paxon side and kill all the Alku.

A war has begun, and Cassi is caught in the middle.

Will she have to choose between the Alku boy she loves and Earth who needs her?
