Ladinas by K. R. Hall

Victor Marinescu was born strigoi being the seventh son of a seventh son. His immortality extended to his parents and siblings. Victor found his mate, and they had a daughter, breaking the family curse. His brothers: Dorin, Garridan, Grigore, Ladinas, Simion, and Cristofor, would now be able to find their mates.
Ladinas Marinescu is the warrior chief of the family, always planning strategies. His security firm has the latest state-of-the-art systems, and his employees were top-notch. His skills were put to the test four years ago when his brother Victor hired him to help protect his mate, Alana.
Lurline, the High Priestess of the local coven, needs Ladinas’ help. Through a vision, she has seen a woman being held captive. This woman is important to Victor and Alana’s five-year-old daughter Inima as she begins to come into her powers.
The woman is not only a Korrigan, but she’s also Ladina’s mate.
