Due to a mistake on my part, a small number of customers who recently bought the title INTERIM from Kobo received the wrong book file. Many apologies for this! Kobo Support tells me they have now updated your libraries with the correct book. If you have a local copy of the book on your device, you may just have to re-download it. Any problems, feel free to get in touch: ironagesf [at] gmail.com.
So sorry for any inconvenience!
