I suspect that it was ending mid-chapter while I was checking out the online preview since it would only show the first "page" of chapter one then flipping would bring up the purchase screen. If it's an issue with their online reader, hey should fix it. If it's an issue with the publisher, they should fix it since some of us don't like buying products sight-unseen. Especially given the prices of ebooks. (Which is ironic since the Vox's lock screen has a quoe about reading being cheap.)
