No prizes for guessing this one's about organ donation! Vida is 19 and has been an invalid all her life because of a defective heart. Richard doesn't hesitate to donate his wife's organs when she is killed in a road accident. But for some reason he feels compelled to meet the recipient of the heart: Vida. She tells him immediately that she loves him and goes on to demonstrate that she has inherited many of the memories his wife had. How they resolve their issues, and deal with the confusing emotions, provides the narrative thread of the story, the controversial theory of cellular memory forming the central theme. It's told in two voices but I personally found the voice of the young Vida unconvincing - she's nineteen/twenty not nine/ten. Interesting enough but not brilliant.
