First Drop

Description for FIRST DROP by Zoe Sharp:

It should have been an easy introduction to Charlie Fox's new career as a bodyguard, working for the personal protection agency run by her ex-lover, Sean Meyer. Their trip to Florida together should have been a working holiday--and a chance to build on the fresh start they promised to make when they last worked together. All Charlie has to do is baby-sit Trey Pelzner, the gawky fifteen-year-old son of a rich computer programmer in Fort Lauderdale.
The last thing anyone expected was a determined attempt to snatch the boy, or that Trey's father and their entire bodyguard team--including Sean--would disappear off the face of the earth at the same time.
Now somebody out there wants the boy badly and they're prepared to kill anyone who gets in their way. Evading them, alone in unknown territory, takes all the skill and courage Charlie possesses.

This is #4 in A Charlie Fox Thriller.
