TRAVERSE CITY, Mich. -- A northern Michigan bookstore is offering refunds to buyers of Harper Lee's "Go Set a Watchman."

Peter Makin of Brilliant Books in Traverse City says some people feel misled about the marketing behind the book. It was written by Lee, the author of "To Kill a Mockingbird."

Makin tells the Detroit Free Press that some readers believed it was a new book by Lee, but "Watchman" was completed before "Mockingbird." Set years later, the book also offers a very different portrayal of "Mockingbird" hero Atticus Finch.

Makin says he's apologized to customers for "being complicit in the marketing." He says his store is based on "intellectual integrity."
