After Battersea Park by Jonathan Bennett

While most of the action takes place in Sydney, Australia, and Toronto, this whirlwind tour of long-separated twins also lands in Hawaii, London, Scotland, Madrid, and Mallorca. The twins — Curt, an Australian jazz musician, and William, a Canadian visual artist — were driven in different directions at the age of four when their drug-addict father separated from their mother. She soon found she could not feed the children and had to give them up. At age 27, they learn of each other's existence and begin a journey that draws them together from different ends of the world.
