Bridging the Chasm is about two brothers, in love with the same girl as they go through adventures and trials spanning almost thirty years. It starts with the tremendous flood that created the Salton Sea in 1905, follows a battle in WW1 that credited the U. S. Marines as a separate fighting force in America, the battle of Belleau Wood. It ends in 1934 with all characters, both major and minor meeting at the construction of Hoover Dam and the build up of a city known as Las Vegas. We follow them through these periods and watch them develop along with minor characters through to the tumultuous ending where lives are lost and the two that should be together do not get together at the end.. It is fast paced with family adventure, danger, violence, humor, a little romance and history. The characters are fictional, the events happened in the past so I guess you could say it's semi-fictional. Sort of like a bridge between fiction and non-fiction.After the end of the book, all 48 states of the United States that contributed men/materials and companies will be listed plus other historical contributions in the construction of Hoover Dam during the Great Depression.
