Decoding Love by Kellie Perkins

Elise Morrow is a genius and she knows it. She also has a massive chip on her shoulder, one she uses to keep everyone around her at bay. With the exception of her two best friends, Elsie isn’t looking to stay on people’s good sides, which is why she’s floored when her boss tells her that she’s been pegged for a special kind of job. She may not be anything more than a computer programmer but nevertheless she’s being sent into an undercover mission unlike anything she’s done before.

Caleb Grant, the job she has grudgingly agreed to, is exactly the kind of man she detests. Rich, arrogant, and too handsome for his own good, he heads an advertising company he can’t seem to keep control of. From the very beginning the two of them butt heads, neither one of them ever considering that there might be something there. As they delve deeper into the mystery of the force trying to discover Caleb’s company, however, both begin to realize that people aren’t always what they seem…
