The Aeronaut is a tense story, full of action, espionage, and romance, set in an alternate version of World War I. Computational machinery has allowed both sides to make great technological leaps that have made trench warfare even deadlier for the soldiers at the front. Some men go to war to defend their homeland or to prove something to themselves but Robert Preston has fled America and joined the French Army to escape heartbreak. He's placed in the 5th Aeronautic Corps, an elite unit of the French Army that specializes in jumping over trenches by means of jet packs. It's a dangerous job with a low survival rate, but Preston is determined to make a difference. Along the way, he meets a man he'd call his best friend and a woman he'd call the love of his life, but a top secret mission behind enemy lines and a heart full of jealousy threatens to tear the three of them apart forever.
