Renaissance: Primordium Book 2

In Primordium Book Two: Renaissance, black geneticist, Truman Justis, the son of Kamau, paleoanthropologist John Lohner's Kenyan assistant in Book One, seeks enlightenment in a universe of shifting realities. Siddhartha meets Rashomon.
When A4-Ni, the mysterious life form nurturing mankind's humanity, dies, humans begin to devolve.

Truman is determined to learn why. But after being transported to 7005 AD by the Shepherd, a UFO of alien design, and given a cure, will Truman step forward as mankind's messiah, when a past of discrimination threatens to overwhelm him?
Confounding his decision is a future populated by proto-humans, "players" of alien origin, and a race of pure humans, the Maraia created by the Shepherd, who wants Truman to insure that they survive intelligent enough so their ancestors can build his creator.

All of this is overseen by the guardian, a golf ball-sized sphere with exotic powers capable of seeing the past and the future. It tests Truman's resolve with shifting realities to the point that Truman questions the nature of reality and whether or not his future, defeating the player Cathcar and helping the Maraia, was of his own free will or preordained.
