Basically, expanding the oneshot that this originally was, I want to follow Remus as he starts at Hogwarts. It begins in year one, and it will stay there for quite a while at least.
In his school years, Remus Lupin became known as a "bookworm": Where he went, he usually went with something to read. But those weren't textbooks, as many of his fellow students originally thought – they were books of great adventures, of other worlds, that drew him in and let him forget about his worries.
But how did this boy grow to love, even to need books so much? When Remus Lupin was a child, there was little he could do; his overprotective father never let him go outside on his own, and least of all was he allowed to play with other children. But he had other friends – he had his books, to take him far away, to different places.
Until one day, a stranger arrives at the Lupins' doorstep, and he might not need his books to find a different world anymore after all.
