His Witch by Harper Phoenix

The alpha of the stone pack vowed he would never love again after the loss of his mate. Hoping to pass the reigns to his son and retire from duty.
But he was in for a shock if he thought it would be easy.
Marissa is a half-born witch with little power, but just enough to wreak havoc on those that wronged her.
A chance meeting and a stolen kiss is all it takes for this unlikely couple to find a new meaning to life.
