I don't know if my mother's completed e-book can be read online because I don't have the relevant information. However, generally speaking, a completed e-book should be a paper book or a local file in an online reading software instead of an online file. If you need to read the completed e-book online, you can try using some online e-book reading platforms such as Amazon Kindle, Google Play Books, and so on. On these platforms, you can search for and download relevant books based on the recommendations of authors or editors.
