While I thought the first book in this series, In the Garden of Iden, was an interesting take on time travel, Sky Coyote did not live up to my expectations. Mendoza's voice was the one heard in Garden, and Joseph's in Coyote; but I found no difference between them and had a difficult time adjusting to Joseph's narration. I find it hard to believe a 20,000 year old man and the Neanderthal "giggle," although this verb appears several times in relation to their dialogue. Perhaps Baker has a more difficult time getting into the head of a male protagonist, but I never believed Joseph was speaking. I do not wish to offend anyone, but I also thought that after the first few pages, the description of Chumash ceremonies was gratuitous and did not move the plot forward.
