Ashley Carter has it all: her dream job, a devoted husband and a baby on the way. Unfortunately, when something seems too good to be true-it usually is. Her husband has been keeping secrets and Ashley, as it turns out, doesn't know Cole Westwood at all. A wish spoken in a moment of anger sends her back to her college years, erasing the life she'd cherished. Back in Yale's Physics department she encounters a reckless, sharp-edged version of Cole-and his twin, Dale, whose death shaped her to-be husband into the man she thought she loved. While they may be brothers, the pair couldn't be less alike: Cole is as volatile as he is charismatic while Dale is a gentle, kind and thoughtful-everything Ashley loved about her husband. With the former pushing her away and the latter falling for her, she finds herself at a crossroads-give her heart to the man bearing her husband's name, or the one who embodies everything she admired about him. Are the growing cracks in Cole's facade enough to allow her a glance at who he truly is? Can she separate Dale from the man she once married? And, most importantly-can she get out of this mess without breaking both brothers' hearts?
