Sirius' Son

To think, the only woman he could ever call 'Mother' was gone, murdered by the one he admired, the one he wanted to meet someday, his own blood. Perseus shoved things in his bag, not paying attention to what. He was going to kill him, his father. Perseus climbed down the rusty fire escape. He was going to kill his father and avenge Sally.

Perseus Black has never played a sport while flying on a broomstick. He's never worn school robes, befriended a giant, in fact, he's never had a place to call 'home' other than an abandoned orphanage. All Perseus knows is a mischievous life on the streets, with a greedy old thief and a ton of books. Percy's room' is a cold London alleyway and he hasn't had a birthday party in four years.
But all that is about to change when a mysterious letter arrives by owl messenger: a letter with an invitation to a wonderful place he never knew existed. There, he finds not only friends, aerial sports, and magic around every corner, but a great destiny that's been waiting for him...if Percy can survive the encounter.
So readers, strap in and enjoy the ride, get ready for twists, turns, and a whole lot of inside jokes.

I DO NOT own the Percy Jackson or Harry Potter series or franchise. I feel the need to clarify that for some reason...
