counterparty is an option, also raretoshi as suggested by DarthCoin below.

I will check back with the community about the options. I need to understand if the person asking is just a degen or if they really value having a tokenized version of the autographed book on their wallets.

As I live far from the community, they asked to have an alternative of a signed book, in digital format. That's why I'm evaluating options and thinking about whether to do it on Bitcoin. I also have been reluctant to incentivize inscriptions.
