Key to the Indian

In The Mystery of the Cupboard, Omri's father found out his great secret. When Omri and his father read together of the terrible plight of the Iroquois people, their abandonment by their British allies and their struggles with rapacious European settlers in late eighteenth-century America, they realize that Little Bear, Omri's Iroquois friend from the past, is in urgent need of help. But how will they go back to the Indian, and what can they possibly give? Father and son struggle to solve the problem of traveling through time together, but they little understand the terrors that lie in wait -- for their Indian friends and for themselves.
