'Rainbow's End' by Rex Beach is a western, action-adventure novel set to the backdrop of the Spanish-American war that will be enjoyed by fans of 'Rough Riders' by Theodore Roosevelt or the film 'Citizen Kane'. The story tells the tale of a time when young men in the West who were old enough to ride would head to East Texas to join Theodore Roosevelt's Rough Riders, and assist with the invasion of Cuba. They would ride to glory and return as heroes, but there were very few who would return home to their families.
