The Covert Guardian - Liane Zane - Bog

Prequel to the Elioud Legacy series
Six weeks 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.
