Their marriage of convenience was supposed to exist on paper. Can these strangers act convincingly in love when the pressure's on?

Piper Paulson's life is finally on the upswing. She has a new job, a BFF roommate, and a commitment to avoid dating after an ex cost her her peace—and her former career. She may not have two nickels to spare, but that's another day's problem.

James Newhouse doesn't have time or energy to deal with . . . well, anything. A hotshot banker with a complicated family, he's determined to keep people at arm's length. His attraction to Piper isn't part of the plan, and neither is adding her to a Family Fares commuter pass as his 'wife' to save her money on train fare.

Too bad their judgment is speeding away faster than their shared train.

Thrown together by chance (and a handful of Elvis impersonators), James and Piper find themselves witnesses to an incident on their commute—'married' witnesses, who may be asked to testify if the crime goes to trial.

Can they keep up the charade to avoid being outed for their lie? And perhaps more importantly, can they protect their hearts in the process?
