Zebras crossing - Rebecca Gregson

Chess has always has a complex relationship with her adopted white family, though from the age of two she's enjoyed every kind of privilege - a good education, a comfortable lifestyle and the crucial love and support of her parents and older sister Judith.
Now in her mid-thirties, she has a happy marriage and balanced children of her own, but something is missing. When she moves from rural Norfolk to multi cultural Clapham, she starts to question her own racial identity. Then fate throws up a reunion with Chess's real grandmother and half sister, and she risks her much treasured security to fully explore her genetic inheritance.
