Twenty years ago, Willow Dwyer nearly died in a school shooting that stole the life of her true love, James. Now she's 40, infertile, newly divorced from a man who refuses to leave her alone, and on the brink of a breakdown. Even after all this time, she still finds herself unable to move forward from the dream of a life and family she lost that day of the shooting. At the suggestion of her therapist, Willow takes up the tango, the dance she’d mastered with James before his death. It seems an innocent enough plan, until Willow dances with Merrick Montagne.

Merrick is a strikingly handsome 20-year-old college student with an uncanny ability for the tango. He makes her heart race for the first time in...she can’t remember how long, and the strangest thing is, he claims he’s been searching for her his entire life. Willow doesn’t know if she believes him, or if she can handle the scrutiny she’s sure to get for dating someone so much younger than her.

Yet no matter how hard she tries, she just can’t seem to walk away. When revelations begin to connect Merrick even further to her past, Willow must decide how much she’s willing to risk for a love that should be impossible, a love she’s not sure she could survive losing again.
