Bookstore app screens

This time, you can see the actual app screens. Book overview screen, List of items in the specific category, and the actual "categories" type of screen where user can see and browse all available categories. I designed additional bottom navigation for each screen displayed here.
A button that allows users to go directly to the list with all available books of the chosen genre for the first screen, standard for e-commerce hovering add to wishlist/add to Basket button on the second, and hovering selection subcategory button for the third one.
I hope someday I'll finish the design and show the actual prototype in action)
