It is a very large book (it's an omnibus of 560 crime stories) but it's not been a problem until now. I'm reading it as a Kepub, downloaded from Kobo - it's not been imported into Calibre or anything.

Initial symptoms: tap on book over to open it, ereader opens the book at a page close to where I stopped reading. However it is entirely unresponsive - the only way out (after leaving it for a few minutes) is to power off and restart.

I've tried signing out and in, and now when I try to open the book I get a progress bar showing no actual progress, then after a minute or so the ereader drops back to the home page.

My next likely step is to import the book into Calibre, make a minor modification somewhere, then sideload it as a new book onto the Kobo and see if that helps.

I can't do that for the next hour or so, though; has anyone any other advice before I try that?
Can you post a link to the book in the Kobo store? When a kepub is opened the first time, a word count is calculated for each chapter in the book. And with the change to show a full book page count based on the rendered pages, it is probably a large book would take to long to render. In this case, I'm a little surprised the device doesn't reboot due to a hung process.

I'm basing this guess on the slowness to open a book I've been reading. This is only 88K words, but, it has a single internal file with 18 chapters. When I opened it, the device would appear to hang, but would come to life after about 10 seconds. Once it is open, jumping around in it is a bit slow as well. I've also done an experiment with a much, much larger book combined into one like this. In that case, it hung and the device rebooted after a while. I suspect your book will be somewhere between these. Looking at the preview will probably give me a hint on this.

It might help to turn off the footer. This might prevent the page count from being calculated for the book. It might also be necessary to turn off the progress bar as that is calculated for the full book as well.
