More than a novel, it is a collection of short stories moving from generation to generation, from the age of slave trade in Ghana to present day USA. This structure is both effective and frustrating. It's effective because it allows the author (and the readers) to explore the connections between colonialism, slavery, black-labour exploitation, civil-rights battles, and today's racism. It's frustrating because some stories are so short that they feel like necessary links, or vignettes, without leaving the time to "grow emotions" for the characters. Some of the plot-patterns in the book were also a bit forced and already-seen (for those who read the book already: black stones, romantic resolution...). That said, it was a fine read and an important one, delving into the horrors of colonialism.
