The Lost Secret of Time — Tiffany Turner

Wanda Stewart's fairy adventures have landed her in 1983, and only her thirteen-year-old mother can help. After befriending the school librarian, Wanda works with her mother and a strange boy to solve a way to jump in time to the present. Hopefully, together they can capture the evil sorcerer Balkazaar once and for all.

But nothing is easy when you are working with fairies. Forced to find her animal helpers in the past, Wanda finally connects with the Fairy Queen and comes up with a plan. But will it backfire when she finds out who the strange boy really is? How will Wanda ever get home to her present time? Only the guidance from a mysterious dragon, finding her cat sorcerer guide, Brewford, in the past and her reliance on her new friends can help Wanda solve getting home and imprisoning Balkazaar for good.
