Showing Change of Heart by Jodi Picoult

Shay Bourne becomes the first person in decades to be sentenced to death in New Hampshire, when he is found guilty of the cold-blooded killing of a policeman and his step-daughter. After eleven years on Death Row, the end is coming for Shay. Until he sees a news piece about a young girl who urgently needs a heart transplant. June’s husband and daughter died at Shay Bourne’s hands, and she thought her greatest desire was to see him killed.

Until her remaining daughter is hospitalised, and she realises that there is something she wants even more: for Claire to live. Shay Bourne is offering June’s daughter a miracle – a second chance. But at what cost?
