We are two student who enjoy reading and decided to make a blog to share the book we read.
Our bussines model is based on that we publish to reviews. The first one is free to all visitors and the second one is for those who pay a mensual subscription.
The difference between the reviews is that the free one just talk about the common knowledge and the premium count we go deeper analyzing the book, the different themes it talks about and the books are relationed with that one.
