Thus far — phenomenal!!!!

UPDATE FOR WP 3.8 — No problems at all with the updates to WordPress. And these folks are great to work with.

I’ve just begun to work with this plugin after searching for weeks for the right way to display a “book page” on an author’s web site.

I can’t believe how well this plugin works. It has all the pieces I wanted plus ones I hadn’t even thought of.

I’m just beginning to utilize it but do check this out. It even offers a widget.

Updated: 10-Sep-2015 No problems using this plugin. It has gone through every WordPress update without problems as well as two theme changes.
