Moon Mated - Shifting Magick Trilogy, #3

Diana Kelly is the baby of three witches and, like her sisters, cursed. She must find her one true mate before midnight on her thirty-third birthday or risk becoming undesirable to everyone outside of her family. With her sisters happily mated and curse-free, Diana holds on to hope for a miracle. However, the clock is ticking, and she's running out of time, and options. Terrence Miles is a lone wolf, loyal only to his Alpha.
When he meets the youngest Kelly sister, he's mesmerized by her beauty and soft curves. His wolf pushes him to claim her, but the man is hesitant. He's never imagined himself mated. Could their mating break her curse and satisfy something in him he didn't know was missing?
