If you don't already know, there were a few additional books written after The Indian in the Cupboard:

• The Return of the Indian
• The Secret of the Indian
• The Mystery of the Cupboard
• The Key to the Indian

That series is essentially fantasy. If he's into that, he might be into sci-fi and fantasy in general. For that age group (and a little older), you have

• The Chronicles of Narnia,
• The Percy Jackson books,
• The Spiderwick Chroniciles,
• The Hobbit (but probably not The Lord of the Rings),
• and maybe even the novels of H. G. Wells and Jules Verne.
