This work across opening and closing the book, and even across ibooks restarts. You can download the widget here:

If you open the zip archive, you can look at the Javascript to see exactly how it works.

A simple wrapper around cookies like this one

would do the work, be sure to replace escape and unescape with more up to date functions though.

sessionStorage may work with the ibook format, but it doesn't for epub3
Thanks for letting us know. I have no experience with ePub, only with IBA. It's weird though that the same execution environment yields different resutls. The only reason I can think of is some difference in the HTML. Have you tried dropping my widget into your ePub as a test? I have no idea whether that will work, but it might be worth a try. That widget definitely works in iBooks on the iPad.
