Everything Comes at a Cost.

The Coalition has been decimated. While humanity teeters on the edge of survival, the crew of the USCS Tempest may be their only hope. But things may have just gone from bad to worse.

Upon arriving back at the planet she grew up on, Evie discovers a secret that throws everything she’s known about herself into question. A lone Athru greets her there, revealing a special connection to Evie and offers to help defeat her own people. But to Cas, this sounds like just another Athru trick to try and eliminate the last of humanity.

Meanwhile Cas grapples with command again after so long, and finds himself questioning even his deepest beliefs.

When it turns out the ship may have to return to Sil space, Zenfor realizes she might have to face up to the consequences of helping the humans so long ago. She already knows she’s been branded a traitor, but will her betrayal get in the way of the mission?

But none of them can truly grasp what they’re in for. The only question that remains is: can they remain united, or will this new thorn in their sides tear them apart?
