Book Library App ~ Dark mode | UI Challenge 001

Hi,
this is my first quick experience with Principle App.

Before the full working year of 2020 starts, so I embark on the leisure challenge of designing the application. I prepared a concept of a mobile application that would help all readers lending books in libraries. Using the application I can read e-books and at the same time I have an overview of the lent books with information to when I have to return them.
