The leader of the True Knot is one of King's best baddies in years � Rose O'Hara, aka Rosie the Hat � a 6-foot beauty fond of wearing a top hat and hellbent on sacrificing Abra for the survival of her species. King's a master at writing characters you love to hate. Rose is like Drago in "Rocky IV," sneering and overconfident, and you can't wait for the inevitable showdown with Abra.
