Peter Kujawinski Hey there - this is Peter, co-author of Nightfall. We're writing a book right now that's set in the same world - tentatively called Edgelands. It won't be exactly a sequel, but you'll see characters like the furriers play an important role. So that's coming out first - BUT, we have a whole bunch of ideas for a sequel (the desert lands, as well as Kana, Marin and Line's struggle to get there), as well as even a prequel. Stay tuned - we're trying to figure out what we focus on next after Edgelands, which we're trying to write as fast as we can!
