Thought I should point out that there's a minor error with the ePub file.
There's a rogue question mark in cover.xhtml that needs deleting. When the book opens it's causing part of the code to display instead of the cover.

Looks good otherwise. Bessie Kyffin-Taylor's not an author I'm familiar with, so I'm looking forward to getting stuck in at some point. Thanks for the hard work
