In case you have not noticed yet I have been hunting for a solid ePub eBook reader for my PlayBook. We have covered quite a few of them as alternatives to the closed Kobo reader but so far many of them have been found wanting. That was until I found Book Reader by Untangled Development. While not perfect Book Reader is pretty darn good and has grown out of the bugs in its original version. The app opens and manages your DRM free ePub eBooks. eBooks are imported and copied into the library when you first open them for faster loading.
Another big plus for Book Reader is that it is selling for a very reasonable $0.99 in App World. Check it out and let us know what you think!
