The Covert Guardian - The Unsanctioned Guardians, #1

Prequel to the Elioud Legacy series   Every hero starts somewhere. She's going to take the fast track from student to trained covert operative. Six months ago, Olivia Markham testified in the grueling murder trial of her cousin Emily's killer. When her boyfriend Jamie surprises Olivia with a trip to Ibiza, party island of the world, her family and friends urge her to go. After all, Emily had been her best friend, the one she'd planned to room with at Brown University her freshman year.  Olivia gets her chance to let loose-only not in the way anyone could foresee.  What was supposed to be a vacation dancing and drinking on the beach trying to move on from her cousin's death turns into a nightmare terrorist attack instead.
As men with automatic weapons and knives move through screaming, swimsuit-clad, and drunken tourists, Olivia can't flee. She has to do something. Even if it kills her. So she stops and confronts a knife-wielding man who'd just slaughtered a young couple.  It was a foolhardy act.  But Olivia's presence of mind and surprising fighting skills don't go unnoticed-or in vain. A team from the Special Activities Division, the CIA's ultra-clandestine paramilitary unit, miraculously intervenes.
What happens next changes the course of Olivia's life forever.  Set six years before the ELIOUD LEGACY series, THE COVERT GUARDIAN narrates Olivia Markham's genesis from idealistic college student to trained intelligence operative.
