Accidentally Fell for My Ex's Uncle by Marie Jessette

Accidentally murdered the bride?
Check.
Forced to marry the cursed Alpha who's lost six wives?
Check.
Now wearing her dress, dragged to his bed, while the pack waits outside for proof he's f****d me raw?
Double check.
Remi was just trying to catch her cheating boyfriend in the act. Instead, she tripped, ripped lace, and cracked a skull.
Now Alpha Nero Blackwater owns her. "Bride for bride," he growls. "You owe me a wedding… and a womb." The curse kills his mates before dawn. Unless he plants an heir fast. But something's wrong.
What if there was never a curse at all?
One night to survive. One claiming to break everything. One Alpha who'll f**k her senseless… even if it's the last thing she feels.
******
"Congratulations, Alpha Nero," she said cheerfully. "Seems the Moon Goddess has chosen your seventh bride."
I choked. "SEVENTH?!"
"The other six are dead," he said flatly.
"And I'm number seven?"
"Correct."
"IS THIS A MARRIAGE OR A SURVIVAL GAME?!"
