Matthew Grayken is young, successful, and dying, which is why he’s about to propose to a total stranger. He isn’t interested in love. He needs a caregiver, a companion, and someone to be his legal voice when he can no longer speak for himself.

Lonely, compassionate nurse Mikaela Compton is intrigued by Matt Grayken’s tender request, but when their friendly marriage turns into love, she rejects the inevitability of Matt’s death and prays for a miracle instead.

Mikaela succeeds in reigniting Matt’s will to fight, but his body is losing the battle, and her determination to save him had causes her to betray the fundamental promise she made him--to help him die peaceably. 

Their last hope at saving Matt's life will require a sacrifice from each of them, and force them to decide how far out on a limb they're willing to go for love.
