The Ghost in the Tower

The fourth book in this magical series. When Glenda Glass evokes the ghost of her evil great-grandmother, Margaret, the atmosphere at Sprite Towers gets exceedingly chilly and the girls' Halloween party turns into something far more sinister then anybody had planned.

With Grandma away, the Sprite Sisters alone must rid Sprite Towers of the Phantom.

The only way they can stop it is to go into the portal in the towers and change the future.

But as Margaret blocks the girls' way out of the portal, the Sprite Sisters look as if they may be trapped forever.

Who can save them now?
