Running Scared (Guardian Security #4)
Desiree Holt

Zak Delaney, partner in Guardian Security, never expected to hear from his ex-fiancée again. After Zoe left, it took him a long time to put himself back together. Now, he must cast aside his hurt and anger in order to protect her. He’ll have to rely on his resources at Guardian to clear her name and use every ounce of his self-control not to fall for her charms again. But as danger closes in, he will have to learn to trust Zoe as much as she trusts him or face losing her again...and this time for good.
