Oh, Thanks for telling me about all this. I also have strange recurring memories of reading those eBooks somewhere which is also why I joined this subreddit. I can remember a Chinese and a Spanish translation appearing on foreign versions of the Geronimo Stilton site in around 2016-2020. What do you think could have happened?
Also, apparently Microsoft's Italian sector distributed free extracts of each chapter of both eBooks (no DRM) in one source we found:

Are these eBooks really lost? I still have telltale signs on some foreign language variants of the Geronimo Stilton website that we need to investigate further.
