Crossing the Line (Territories, #1)

Real estate agent Emma Lowe receives a broken piece of a rare jewel along with a mysterious photograph from a complete stranger when she travels to London for her estranged father's funeral. The jewel unleashes a physical strength she's never experienced but also erotic sensations beyond her wildest imagination. Obsessed, she keeps the gem a secret. That is, until she returns back to Los Angeles and two men turn up to see a house on the same day...only it's not the house they are after. As she is thrown into the seductive realm of very dangerous and desirable men, shady detectives, and a long lost relative she never knew existed, all wanting her for different reasons, Emma has to decide which one to trust. And face the truth that the one closest to her may be her biggest enemy.
