Mothers talk about impossible choices. But, as I look at my daughter in a hospital bed, her red hair fanning out around her, my heart feels literally torn in two. Should I risk my son’s life to save my daughter, or keep my little boy safe and watch my precious girl slip away?

My darling daughter Tara has a rare form of cancer and there’s nothing I can do. At eleven years old, she’s already been so brave, but my sweet girl is hanging on by her fingernails. She has one last chance: a bone marrow transplant from her little brother. But nine-year-old Callum has an autoimmune disease, and there’s a chance it will put him at risk.

It’s life or death for one of my children and I have to make this decision alone.

I wish there was someone by my side to help me and my family through this terrible time. But life has hit us so hard recently. A few months ago, my beloved husband died in a tragic accident and now I might lose Tara too. All I want to do is to protect my children: so much has been taken from us already. I hope for a miracle, but my daughter is running out of days, and I have to choose.

If I make the wrong choice, will I lose one of my precious children forever?

Totally heartbreaking and gripping fiction about parenting, loss and finding light in the darkest of times. If you love Jodi Picoult, Kate Hewitt and Jojo Moyes, this novel will stay in your heart forever.
