I purchased a book from Amazon Kindle and had it sent to my PC. On my PB I use Book Reader for EPUB which I am very happy with. The Book Reader notes says it is compatible with Kindle so I transferred the book to my PB. I now see that it is a .lrf file and it is not read compatible with Book Reader. What must I do to be able to download or convert the Kindle book to a Book Reader format. I would prefer to continue using Book Reared as opposed to downloading the dedicated Kindle app.
