Quite happy to get this done as I'm neither very good at nor fond of technical, finickity things. Fortunately , formatting the Smashwords version did almost everything necessary for Amazon too.
I think that's the last concrete piece of work needed on Bane of Souls. From now on I'll be splitting my time between writing Altmortis and marketing Bane of Souls. Very much looking forward to getting back to writing, especially as I'm still just a quarter of the way into the first draft, which is always the most fun.
Edited extra bit: Bane of Souls is also now out on Diesel, in ePub format (used by most eReaders, though not the Kindle). You can buy it here.
