Query: Too Inplausible

Admittedly, I purchased this book as an easy read for a vacation in Central America. The basic story line was intriguing: an expedition disappears, without a trace, in the uncharted Amazon. For the first 200 pages, the book was difficult to put down, as the expedition enters the rainforest and begins its quest. But, as the mysteries are revealed the drama fades. The characters don't react as real persons to what they are subjected to, instead soldering on in a cliched way. Bizzarre creatures take over the story. Despite the sometimes tedious and unnecessary detail and the collapsing and unrealistic plot, I read on to the end, hoping the story would redeem itself. I wanted to find out about the mysterious Ban-ali tribe that haunts the book from its inception. But, the mystical Ban-ali tribe, when they are finally revealed, are uninspiring, one dimensional and never seriously developed.
