Dredge's Enchanting Mate (Saber Chronicles Book Six). Saber Chronicles, #6

Dredge has spent the last several decades of his life righting the wrongs of his warlock family, leaning away from dark magic and doing everything he can to spread goodness in the world. But when a mystery group attacks the hotel where he lives, he'll have to use every spell in the book to help keep the residents alive. Sabertooth tigress Taryn is puzzled by the mating dreams that come to her after her brother finds his truemate.
The dreams aren't romantic like she thought, but instead are plagued with danger. When she finally meets Dredge, she can't help but worry that they're not safe, no matter how strong and powerful her new mate is. Dredge didn't think he'd get a truemate, let alone a beauty like Taryn, and it's now his life's mission to make her the happiest female on the planet. But danger seems to be around every corner.
Can Dredge keep Taryn and her family safe and find out who's behind the attacks, or will his magic fail him when he needs it most?
