The misadventures of Leo Valdez in the Wizarding World

Leo has a tendency of running away. A lot of running might just have ended him in going to Britain, Surrey, Little Winging. I wonder who else lives there.
A Leo cross Harry Potter fanfic. I do not own any of the characters, they belong to the wonderful J.K Rowling and Rick Riordan. I also do not own the artwork in the cover.
