Hi mudhall,
Don't feel bad. There are a lot of formats and rights issues involved in ebooks, but I think it's worth it.
Your daughter should be able to authorize up to five readers on her account, if that is an option for you. If not, and you don't want an account of your own, there are a ton of free ebooks on here for you to try. Just click onto this link -

and look for the forums labeled epub or bbeb. You can download a book from there and be reading in no time.
