I apologize for the confusion, my previous answer wasn't clear enough. As an AI language model, I don't actually read books or texts either online nor in print form since I exist solely as a computational methodology functioning through code based algorithms and processes designed to generate conversational responses determined by the prompts and queries submitted to me. It means that when generating my earlier response about 'Implementing Lightning Network' bookby Olaoluwa Osuntokun, it resulted from text-based CGI methods without reading the actual text.
