The Playbook by Maggie Jane Schuler

Things aren’t always what they seem…
Some claim college is four years of trivial experiences, and a means to an end. I believed it when I structured my days in an endless set of routines. Then, I befriended Adriana. She brought with her baggage which would change my perception forever.
I also met Blake Angel.
What started out with some innocent flirting, wedged me, Sam Sawyer, under his wing for protection. Criminals stalk our every move, like a long game of cat and mouse. His playbook—well, ours—starts to unravel in front of us. He rules the world as coach, mentor, protector, and possibly my future. Over the course of time, my protector turns into my lover. Blake vows to save me and turn the world upside down to get what he wants. But this mess owns us, and somehow, we need to solve this puzzle of betrayal smothering us.
If not, we may lose this game and our happily ever after.
