Honor. Duty. Patriotism. What drives a pony to serve his or her country?

At a barely legal age, Flash Sentry enlists in the Equestrian Royal Guard. Away from home and everything he's ever known for the first time in his life, Flash's experiences help shape and forge him from a colt to a stallion. Pride, commitment, love, courage, and an unshakable loyalty to his brothers in arms.

But then the unthinkable happens and tragedy strikes. And upon his return, he must come to terms with what he's done and what he's seen. War has changed him. Haunted by nightmares and hallucinations, Flash struggles with regaining a sense of normalcy again. But although the road to recovery is a long and strenuous journey, he doesn't have to go about it alone.

Not all enemies are tangible. Not all wounds are visible. Not all wars are waged on the battlefield.
