Bookstory App For People Who Love Reading

Hello friends! Lately I've been lacking inspiration for reading - so I decided to create my version of mobile app which will motivate you to read more. You also can challenge your friends to have some fun with it too! The app curates book selection to your tastes, which will help you to find stories you'd love much easier.
What do you think about the design? I will be happy to hear other peoples opinions on it:D
