The Spy (Billionaire Royals #7)

Lucan knows everything about everybody. No one really knows to what depths he descends to take care of the Valdez family. He has secrets of his own, a past he keeps carefully hidden from even his brothers. His worlds collide when a stunning woman shows up no one has ever seen before, no one except Lucan.
Sammy knows her appearance in Torren will create some waves, especially with Lucan. But she doesn't know how else to get his attention.
