The book can be downloaded from archive.org (https://tinyurl.com/sharpley). It is in no way as profound as LLPSE, but it gives a good idea of how the language works and can serve as a good and enjoyable introduction into Latin. The story itself is fun and engaging: abbots, nuns, drunken monks, naughty disciples, perfidious Danes, treachery and murder, pages and pages of sheer delight. Audio files for the book can be found, but the recording is in church pronunciation. Drawbacks: no macrons and decidedly not enough exercises.
