Unlocking The Spell by E.D. Baker

Annie has helped her sister Gwendolyn (otherwise known as Sleeping Beauty) wake up from the 100-year curse by reuniting her with Prince Beldegard, so you’d think that things would be back to normal.
Think again! The beloved prince is stuck in the body of a bear and the only way that Annie can be free of the two irritating lovebirds is to come to his rescue – she must find the evil dwarf who cast the spell, and quickly . . .

Luckily, Annie has her own handsome prince to hand – and many tricks up her non-magical sleeve.
