The Indian in the Cupboard: It’s Omri’s birthday, but all he gets from his best friend, Patrick, is a little plastic Indian toy. Trying to hide his disappointment, Omri puts the Indian in a metal cupboard and locks the door with a mysterious skeleton key that once belonged to his great-grandmother. Little does Omri know that by turning the key, he will transform his ordinary plastic Indian into a real live man from an altogether different time and place! Omri and the tiny warrior called Little Bear could hardly be more different, yet soon the two forge a very special friendship. Will Omri be able to keep Little Bear without anyone finding out and taking his precious Indian from him?</p> 

The Return of the Indian: It’s been over a year since Omri discovered in The Indian in the Cupboard that, with the turn of a key, he could magically bring to life the three-inch-high Indian figure he placed inside his cupboard. Omri and his Indian, Little Bear, create a fantastic world together until one day, Omri realizes the terrible consequences if Little Bear ever got trapped in his "giant" world. Reluctantly, Omri sends the Indian back through the cupboard, giving his mother the magic key to wear around her neck so that he will never be tempted to bring Little Bear back to life. 
 
The Secret of the Indian: As his adventures with Little Bear continue, Omri travels from the French and Indian wars to the present, and then back to the Old West at the tum-of-the-century.

The Mystery of the Cupboard: In The Secret of the Indian, Omri vowed to lock his magical cupboard forever. But now, in The Mystery of the Cupboard, he finds an old journal written by his great-great aunt that reveals that Omri is compelled to open the cupboard just once again.
