The Fate of Black Hearts by Zoe Forward

Dom gave up everything for Evie—his magic, his freedom, even her memory. Bound by an ancient prophecy, he knows that if she ever remembers loving him again, the world won’t survive it.

But letting her die was never an option.
Evie remembers nothing about the dangerously powerful mage who destroyed her life… only the way her pulse stumbles whenever he’s near. As alpha of her lycan family, she’s determined to reclaim the memories stolen from her—even if she has to kill the man guarding them.
Because Dom knows everything: her secrets, her scars, the desires she can’t control. Every touch between them feels forbidden. Every glance sparks a hunger that’s terrifyingly familiar.

She needs him dead to break the spell.
He needs her to never remember they were once in love.
Because if she does, their passion won’t just consume them—
it will destroy the world.
