Daisy Potter has to find Tom Riddle's Horcruxes and destroy them. But this is no simple feat when she is taken by Riddle and is forced to attend the freshly taken-over Hogwarts which punishes their trouble-makers by forcing their classmates to use the Cruciatus Curse on them. As troublemaker-in-chief, Daisy is already in danger; but Riddle is not giving up on his chance to make Daisy fall in love with him and have his children.
And when Daisy eventually manages to escape, it's not much better. When you're on the run with four other pranksters, things are bound to get crazy. Daisy Potter, aka the powerful angel Daisiel, has to deal with her childish best friend, her thinks-he's-so-damn-funny boyfriend, her hot-as-hell boyfriend's brother, and being humanity's only hope as the Chosen One.
But when the Battle of Hogwarts comes up ... who will fall?
