Hi @DariusRowser,
Not sure if you realized it or not, but you posted your question to the Instructure Community, a global site where users of Canvas and other Instructure products collaborate to help each other. Unfortunately, this is a question you'll really need to ask your teacher. There are a lot of different ways and places an eBook link could be placed in Canvas, and we don't have any access ot your acount or course. If you reach out to your teacher via whatever methods they make availabke to you (like the Canvas inbox, email, chat, phone, etc), they should be able to tell you how to access the eBook for your class.
Hope this helps, good luck!
