Torn Apart — Gayle Parness

Five years have passed. Jackie, a young cheetah shapeshifter, and Garrett, her vampire lifemate, are trying to deal with the usual problems faced by any new parents. Even those with supernatural powers.
However their son, Charlie, was born with a rare bloodline, a cross between two warring supernatural groups, fae and demon, both sides planning to use him as a pawn in their impending war. Because of the prophesy regarding the role he plays in the war, he's guarded by warriors and demi-fey, watched by fae lords, and slotted to be trained throughout his life to use every weapon at his disposal to protect himself, his family and his allies.
Jackie knows it isn't enough. In her usual style, she takes it upon herself to keep her son safe, even if it means spending time in a realm far from the family she loves, angering the males she's pledged her life to protect.
