Sort of interesting plot and subject, "Blood Colony" is what I would call African-American Science Fiction. The premise is that an African, 2000 years ago receives the majic "living blood" of Christ, drained from him at the crucifiction. This living blood cures disease and give immortality. Unfortunately there is a second group of evil whitemen from Rome who also have the blood, and want to destroy the black folks who have it. Uh huh.
Evidently, this is the third novel on the subject, and combines a lot of historical and biblical history woven into the plot.
Overall, I liked it.
