Shevlin Axton is not the kind of man who dies, but since the Imperium grounded him after a grisly crash, he might as well be dead. Once a famed ace pilot and now the young commander of a clandestine roving war machine, he spends his days hiding from the public eye and trying not to think about the squad he led to their deaths one year ago. When he receives news of a field hospital near the front-line trench ravaged by the same unknown magics that killed his squad, Shevlin must commit treason against his own country to uncover the truth or find himself implicated in a conspiracy.

His ex-boyfriend, an eager-to-please rookie, and a subversive supersoldier might be the only ones willing to follow him into danger knowing what happened to his last squad. Shevlin has all three of them convinced he can end the war single-handedly-but he’s not the self-assured ace he used to be, and he can’t smother the rumors that the gods curse anyone who flies with him. Taunted by enemy generals, pursued by secret police, and beset by the consequences of the past, Shevlin and his few remaining allies must divine a plan that will compel Death himself to choose a side.

Weird, queer, and pulpy, Oath and Entropy is a queer deconstruction of military sci-fi, delving into the bonds that hold people together in a system that’s collapsing around them.
