Hi again, all. Thanks for your comments - it appears as though I can't read this book outside the Kobo ecosystem, would that be correct? It doesn't strike me as particularly excellent business practice not to specify this before the point of sale, but I suppose that it is what it is; and really, I'm sure I'd have actually noticed something somewhere, had I known where to look.

I've grudgingly downloaded the Kobo app onto my Nexus 7, and I'm able to open to Percy Jackson omnibus there without issue; it looks as though my 'comic book device' will enjoy a short change of pace to an ereader until I finish this series. I have to say, though, that until I discover where I can find out whether or not books are accessible outside the ecosystem (DRM aside), I'm now exceptionally wary of continuing to shop with Kobo...
