HEART-STOPPING TERROR Dr Abby Di Matteo has made the best - and the worst - decision of her career. Instead of giving a donor heart to the wealthy patient it's been reserved for, she uses it to save a dying boy's life. Luckily, a new heart appears that's perfectly suited to the original patient, and the furore dies down. But then Abby discovers that the organ has been obtained illegally. Defying the hospital's commands, she starts her own investigation... And uncovers a murderous conspiracy that will threaten her very life . . .
