Query: A Gripping Read

This book contains gripping accounts of all known deaths in the Grand Canyon. The intro contains a warning that the stories may keep you up past your normal bedtime--I found this to be true!The book is thick, does drag a little in the middle, and contains some grammatical errors, but these are overshadowed by the enthralling nature of true accounts of fatalities and near fatalities in the grandest of the seven natural wonders.Keith W.
