Riley Walsh doesn't want a fake girlfriend but he needs one.

It's the only thing he can do to deal with an ex who doesn't believe it's over and years of pining for the most off-limits woman in his world-his sister-in-law.

She's left picking up the pieces of her ex's humiliating lies and manipulations, rendering her reputation in her ultra-competitive surgical residency program seems beyond repair.

Two months. Four dates. Five at the most. But possibly six. Definitely no more than six. Only the appearance of a romantic relationship is required. No other benefits involved in this agreement.

One weekend to unravel the entire plan.

After waking up in bed together-very naked, very hungover-the terms and conditions of their arrangement no longer apply. But that doesn't mean they're finished with each other.
