The Secret of the Indian — Lynne Reid Banks

THE MAGIC CONTINUES...
It began with the highly acclaimed classic THE INDIAN IN THE CUPBOARD when Omri discovered he could bring to life the miniature plastic Indian, the American cowboy, and his other toy figures. In THE RETURN OF THE INDIAN, Omri found he could even transport himself and his friend Patrick into the dangerous 19th-century world of their miniature friends.

Now, in an incredible new adventure, Omri and Patrick are forced to share their secret with Patrick's cousin Emma. All of England is threatened by the disastrous cyclone they have brought back from the old American West, and Emma may hold the key to survival.
