ABANDONED. Chapter book: Evil amulet makes boy invisible??

[Vintage]

I am posting this for someone on Facebook.

It had a boy who found an amulet that when he wore it, it made him invisible. And similar to the Lord of the Rings ring, the amulet turned out to be evil.
It would have been a chapter book, but it likely wouldn’t have been more than 100 pages, as I remember reading it in early elementary school.

Does this sound familiar? If I am supposed to post this somewhere else, I apologize.

Thanks, Kelly

I'd look at John Bellairs. All the amulets in his books are evil, and I think there may be 1-2 that make people invisible. They're shortish chapter books (max 200 pages).

Thanks. I'll have her check it out.

Sorry, but this is a huge group so we don't allow cross-postings from other social media sites or groups. This should be a book that you read. Closing thread.
