Black Thorns by Rina Kent (Thorns Duet #2):

A lie turned into a nightmare.

She broke my heart.
Broke me.
Broke us.
Only one thing could mend the gaping wound she left behind.
Her.
Naomi.
All mine for the taking.
All mine for owning.
All mine.

Black Thorns is a dark romance book that contains dubious situations some readers might find offensive and/or triggering. This is the last part of a duet and is not standalone.
