This book follows the lives of Violet, Klaus, and Sunny Baudelaire. After their parents' death in a fire, the children are placed in the custody of a murderous relative, Count Olaf, who attempts to steal their inheritance and, later, orchestrates numerous disasters with the help of his accomplices as the children attempt to flee.
This book was also adapted into a movie - I remember being able to watch it on TV again and again every holy week (I don't know what the stations are thinking of but they always have this movie)
