Fairy Gold — Gwyneth Rees

In the fourth exciting and charming Fairy Dust novel, Lucy teams up with tooth fairies

Lucy can't believe her eyes when she wakes in the night to find Goldie and Bonnie -- two tooth fairies -- on her pillow. The fairies tell Lucy that their job is to collect children's teeth, replace them with fake ones, and make a potion that creates golden Goodness. But there is trouble in fairyland. A selfish sprite wants all the Goodness for herself instead of sprinkling it around the world. With the help of the Tooth Fairy Queen, can Lucy and her new friends stop the thieving fairy before the gold has all gone?
