## Overview

MyReads is a React book-tracking app: users browse books grouped by reading shelf, move books between shelves, and search for books to add. App owns the book collection and loads it from the Books API; shelf changes update the API and refresh that collection. Search results are displayed as books with shelf controls, while book cards also provide a detail preview. The README documents the API’s getAll, update, and search capabilities. Some less-central files are represented only where the sampled imports establish their role.

Main entry points: [`src/Components/App/App.js`](https://github.com/egstar/myreads/blob/master/src/Components/App/App.js) (App state and routes), [`src/Backend/BooksAPI.js`](https://github.com/egstar/myreads/blob/master/src/Backend/BooksAPI.js) (Books API client), [`src/Components/Search/Search.js`](https://github.com/egstar/myreads/blob/master/src/Components/Search/Search.js) (Search controller), [`src/Components/Book/Book.js`](https://github.com/egstar/myreads/blob/master/src/Components/Book/Book.js) (Book card and preview)
