HOMINIDS, the first novel in the trilogy, was a very well done novel about the accidental opening of a portal to an alternative universe where Neanderthal's became the dominant hominid. It explores the Neanderthal society and the various differences between the two cultures, human and Neanderthal. There is also very good character development in HOMINIDS, which really drives the rest of the trilogy.

HUMANS in some ways has the weakness of a second novel in a trilogy because there really is not a lot of plot development. But it is an absolutely hilarious social satire on human society, with digs at the United States' culture from a Canadian point of view. HUMANS is the novel I enjoyed the most of the three.

HYBRIDS is a good novel and conclusion to the trilogy but somewhat of a let down. Sawyer presents some really terrifying situations for both Neanderthals and humans but the emotional punch just isn't there. It's like watching a disaster with complete emotional detachment. The build up and mystery needed to evoke the kind of emotions to drive the story is missing.

Nevertheless, this is a good trilogy and recommended.
