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 companion and nurse to ease his last days, and a legal voice to enforce his wishes when he no longer can.

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

Mikaela reignites Matt’s will to fight the disease, but he needs a miracle. Mikaela believes she knows where to find one, but it will require her to leave Matt at the hour of his greatest need and break the fundamental promise she made to him—to be his advocate and enforce his last wishes.

Mikaela faces an excruciating truth—that love brings exquisite joy, but it also requires the agonizing courage to go out on a limb.
