Irish War Cry by Victoria Danann

Rosie hired Irish elf twins, Sheridan and Shivaun O’Malley for the newly formed Department of Interdimensional Trespass. They were wild and nearly feral, raised in the New Forest Preserve with no contact with the modern world until Black Swan made them the only female hunters other than Lady Elora Laiken. When Sher was assigned as Finngarick’s partner, they were both stunned to find they weren’t only partners, but fated mates. Blissful fated mates who enjoyed each other for the span of less than a month before Sher was abducted by one of the very demons they hunted.
Meanwhile, the “Wild Bunch”, Black Swan’s new nickname for Rosie’s hunters, has its own problems.
