Amazon Kindle:Improve Kindle app design

Amazon provides a Kindle reader app so that users can read e-books on the mobile devices, even without owning a Kindle device. The primary goal of this app is consumption, but discovery also matters. This is the screen shown to users under the 'Explore' tab, when trying to discover new book titles. Improve its design so that it is more meaningful to users, than just a listing of categories, as is done presently. The goal is to make book discovery a delight. You can add elements and completely redesign this screen if needed. Note: You need to design only 1 screen of the mobile app (one fold only). Please do not use any annotations or explanations in your designs
