Liv wants to be the mother she never had

Liv has always dreamt of the moment she will hold her own baby. But just at the moment her new life – as a devoted mother to Max, a loving wife to Justin – should be starting, it looks like it may be ending. An undiagnosed heart condition, worsened by her pregnancy, has thrown her whole future into doubt. If she doesn't receive an urgent transplant, she won't live much longer.

But what if she can't be here for her son?

As she grows weaker, her determination to raise her baby grows stronger. Without her to protect him, what future does Max face? Slowly Liv begins to ask herself a terrible question: she needs someone's healthy heart to replace her failing one. For that to happen, an accident would have to befall someone else. But what if she could engineer that accident herself? What if she could choose someone to die in order that she could live?

If the end of someone else's life offers you the chance of saving your own, whose life means the most?

A powerful and completely gripping novel about love, sacrifice and how life forces you to do the unthinkable.
