Query: Great Read

This book is really eye-opening. I learned a lot about slavery in the US, and by extension, a lot about African cultures.The first half, about African abductee Kunte Kinte, is great. The second half, about Kunte's descendents, was less interesting to me. Throughout, the prose is about on par with Michener.All in all, a great read.
