First Lie Wins by Ashley Elston

The identity comes first: Evie Porter. Once she’s given a name and location by her mysterious boss, Mr. Smith, she learns everything there is to know about the town and the people in it. Then the mark: Ryan Sumner. The last piece of the puzzle is the job. Evie isn’t privy to Mr. Smith’s real identity, but she knows this job isn’t like the others. Ryan has gotten under her skin, and she’s starting to envision a different sort of life for herself. But Evie can’t make any mistakes—especially after what happened last time. Evie Porter must stay one step ahead of her past while making sure there’s still a future in front of her. The stakes couldn’t be higher—but then, Evie has always liked a challenge. . . .
