Kathryn the Gym Fairy (The School Day Fairies #4)
It's time for Jack Frost to learn his lesson!
Best friends Kirsty Tate and Rachel Walker usually only get to spend vacations and holidays with each other. But for a special week, they'll both be going to the same school! It's a good thing the two friends are together. Jack Frost is causing trouble at the Fairyland School--and the School Day Fairies need help!
Kathryn's magic gym badge is the only one still missing. Rachel and Kirsty have to find it so that school days are fun for everyone again!
