Heaven Sent by Delaney Diamond

Friends become lovers as they uncover the heinous actions of an evil empire’s plans.

Camila Hughes, a digital magazine columnist, spends her free time working with the homeless in Las Vegas. When one of them turns up dead in what police dismiss as a suicide, Camila suspects something darker at play.
Alejandro Sanchez, a skilled explosives expert and Camila’s childhood friend, has always kept his feelings for her in check. When intruders invade her home, his protective instincts turn lethal, and he vows to stay by her side to help her unravel the mystery surrounding the break-in, and her friend’s death.

Sparks fly between them, igniting feelings they’ve both kept hidden for years. And when the enemy comes for Camila, Alejandro has to teach them a lesson: Never threaten the woman he loves.
