The Potter story so far: Book 1
There are mysteries galore afoot. Someone sends Harry his father's invisibility cloak.
Hogwarts is home to something that is very dangerous, and Harry and his friends go about snooping Famous Five style to find out what and who is desperate to lay his hands on it and why.
There are dark nights in forests with hooded creatures drinking Unicorn blood, there are brushes with huge Trolls and dark brooding mystery all around.
Harry also has to deal with the evil Draco Malfoy from Slytherin house, who becomes Harry's sworn enemy.
