In New York City Newt Scamander unexpectedly finds his most intriguing “creature” yet - a feisty muggle girl.

Elizabeth Roberts was a totally ordinary 13 year old girl you could probably find anywhere in the city. Kind, if a bit naive, good at school and loving to hang out with friends. That is... until she accidentally walked into the path of a certain young genius right as he attempted to time jump for the very first time.

Most witches and wizards think Harry Potter is an only child and so totally alone after his parents death. But that's not true. Born in secret, Harry actually has a younger sibling. With no great prophecy hanging over her head and overshadowed by her brother, what part will she play in this magical world they were suddenly thrust into by a giant?
