Debts and Diamonds (The Deana-Dhe Duet #1) by Bea Paige

Book #1 in The Deana-Dhe Duet

Tropes: Dark Bully Romance, Paranormal Romance, Why Choose Romance, Reverse Harem, Enemies to Lovers, 

Arden, Lorcan and Carrick are the men everyone fears...

They are known as the Deana-dhe.
Dealing in debts, they steal information and they manipulate.
To them I am Cyn.
I’m their original sin.
The mute girl they never wanted to be drawn to.
The girl who put a spell on them, who became their cailleach.
You see, I’m a modern day witch, skilled in the art of alchemy.
A long time ago I made a deal with the Deana-dhe, and they’re back to cash in on my debt.
But if I’m the apple they never wanted to take a bite out of, then they’re the snakes willing to use me for their own gain.
They want me to make diamonds, a drug that has the ability to heighten the senses, and manipulate emotions.
They want me to reverse the spell I put on them.
But how can I?
I may be a witch, but there’s no f*cking with love.
