Hopeless Necromantic by Shiloh Briar

SHE RAISES HELL. HE RAISES THE DEAD. WHAT COULD POSSIBLY GO WRONG? 

When new recruit Helspira takes on the doomed mission that no other soldier wants, life—and death—start to get a little complicated. Helspira must play escort to Sikras—a frustratingly handsome necromancer with the power to raise the dead—as he attempts a mission that he's failed twice before; stopping an undead army at the edges of the kingdom. 

No one thinks he will succeed. Not even Sikras. But the more time the two spend together, the more they find they can imagine a brighter future. As secrets come out and the two grow closer—and Sikras's lively skeleton companion Benjamin tries desperately not to be a third wheel—will Sikras' and Helspira's changing feelings for each other be enough to overcome the growing danger?

RAISE A GLASS. RAISE THE DEAD. JUST DON'T RAISE YOUR HOPES.
