Wellspring of Magic — Jan Fields

What happens when six ordinary girls accidentally open a secret door into another world?

It doesn't take long for adventure -- and danger -- to find them. Their quest brings them face-to-face with gigantic grizzly bears claiming to be guardians and protectors, green-skinned folks offering magic and help, a scaly river dragon, killer plants and monster-sized spiders -- things none of the girls expected to face in their summer adventures! And to top it off, they are supposedly the long-awaited princesses who have to use their special power's to restore the magic in order to get home. . .

Will they master their new powers in time to turn back the dark forces that want to trap them forever?
