Blood and Brothers is a fantasy book set in a futuristic world different from our own. Rogue Scientists who have fled Earth to do research into genetic manipulations find a world wrapped in extremely powerful energy fields, allowing them to power their technology. This same technology allows them to have grand, flying craft with sails grabbing not just the wind but power from the air. The story is oriented around two unlikely friends: Darian Carver, a human, and Max Ford, a Mantarian. Mantarians are one of the engineered races and are based on an equine model. The two friends who are as different as night and day are quickly shown to be best friends, as two unalike people can often become. The young men experience exciting but tough trials, exposure to both good and bad mentorship, and challenges of both the body and the spirit. They learn what is most important to them, who they can depend on, and the type of people they want to become.
