'I would do anything for you to get well again, baby girl.' It's a promise. Even though it means asking her father for help, going back there, risking everything. Whatever the cost, there's no hesitation in my mind. Because that's what you do when you're a mother.

Single mother Anna's six-year-old daughter Libby is her whole world. Having escaped a marriage that was threatening to destroy her, Anna has managed to get their lives back on track. Looking at Libby's sweet, heart-shaped face, Anna is filled with hope for the future. They have each other and nothing else matters.

But then Libby gets ill, with a rare disorder that means she needs a transplant from a relative if she's going to survive. And when Anna discovers she herself isn't a match, there's only one person she can turn to.

So she picks up the phone, and dials a number she hoped she'd never have to call again. The man she once ran from. Her daughter's father. She's scared he'll want them to come back home, scared he'll be able to break her all over again. But Anna knows what she has to do, what any mother would.

Because if there's a chance to save your daughter's life, wouldn't you do whatever it takes?

An unforgettable, heartbreaking and ultimately uplifting story from the bestselling author of My Husband's Daughter, this novel is perfect for fans of Jodi Picoult, Diane Chamberlain and Jojo Moyes.
