It may seem like World Book Day is all about kids dressing up at school, and of course to encourage their love of reading. But adults can also enjoy the day too by celebrating all things books in any way they want.
It's also an opportunity to rekindle your very own love of reading, or to discover the joys of a great novel for the very first time.
To help you do either of these things, Amazon is treating customers to thousands of Kindle Books for just 99p.
