This book is great for those just starting out in latin! The vocabulary is very simple and repetitive, which is helpful for learning how the different word endings are used in context. There are also a few pictures throughout. I have a pdf scanned from a 1933 edition.
I've only been learning latin for a few months (casually) and I was able to read the first few chapters without even referencing my dictionary or conjugation cheat sheet. I'm currently halfway through & the sentences are becoming progressively more complex, but I'm still able to follow along easily.
The actual 'plot' such as it is, is pretty dull, but being able to just pickup a book in latin & read it is worth it
