Cast from his Stable for reasons he can barely comprehend, Lucky Thirteen must learn to survive in a dangerous and unknown world.

Armed with nothing but a robotic leg, a mysterious prototype Pipbuck 5000, a 10mm pistol, and his polarized luck, he will travel to the northern reaches of Equestria, to the frozen wastelands near the fabled city of Lost Angels, to destroy a dangerous artificial intelligence and earn acceptance back into his Stable.

On his way to these lands, Lucky will befriend an unusual assortment of traveling companions, fight off threats from within and without, and uncover the secrets of a time before his own.

He doesn't know if he will succeed, he doesn't know what awaits him on his journey, but what Lucky Thirteen does know, is that he is no hero.
