The Onyx Covenant by Mila Young

HE ONCE REJECTED HER HEART. NOW HE HUNTS FOR IT.

Lyra Mooncrest swore she’d never forgive Theron Shadowmane—the wolf shifter who shattered her soul and left her bleeding.
Now, with the Harvest Ritual looming, she’s forced into enemy territory, tasked with uncovering ancient magic that could save her dying pack.
The catch?
She must work alongside the very man who once crushed her…and who would see her fall again.
The ritual is no sacred tradition—it’s a blood-soaked battleground. Rivals lurk in every shadow, and Theron stands at the front of the line, ready to carve out her failure with a smile.
If Lyra can’t outfight them, outwit them, and outlast her own broken heart, the Mooncrest line will die with her.
Because in this game of survival, mercy is a weakness.
And when the ritual begins, there’s only one rule:

HUNT OR BE HUNTED. EITHER WAY, SOMEONE BLEEDS.
