Kobo software on Amazon Fire?

Just curious, can the Kobo software still be installed on a standard (non-rooted) Amazon Fire (HD 6)? I keep finding links to the Kobo Apk, but they seem dead, and I'm leery of trusting some of the sites anyhow. What's odd is that GetJar worked fine for the Nook software, but when I try to download the Kobo software I get redirected to the Amazon App Store by the Fire which, of course, goes nowhere.

Thanks for any pointers.
