All In - The Nate Thrower Series, #2

Thrower is hired by Logan Yarbrough, who is the agent for model Monica St. James. She has been receiving threats, but she's also scheduled to leave the country to go on some photo shoots across Europe. While Thrower and St. James don't mix well at first, they soon develop an affection for each other. While in Europe, they're in almost constant danger. And in order to get out of this, he's going to have to figure out who's behind the threats on St.
James' life. Once he does, the answer is surprising, and not what he suspected. But he'll do what it takes to protect his client and take the fight to his enemies, no matter what it takes.
