Built a side-project for fortnightly book reading

Heard all sorts of complaints from people around me regarding reading books: - can't find something I like - don't know where to start - don't have the time for it - it's annoying not knowing how long the chapters are So together with a friend we made a web app called Alfread (https://alfread.io) where people can read a different book every two weeks. Sort of like a book club. Current books are taken from the public domain (so copyright free) and reading is free. You can read without having an account, but creating one will help save books in your bookshelf and add bookmarks. Any feedback?
