14. A book based on a true story.
Once again, you've got a lot of room to play with this. As long as the book is based on events that actually happened, you've got yourself a book for this week's challenge.
But we'd like to draw your attention to a few challenges that are coming up shortly, as you may need to indulge in some advance planning.
Week 16 in the challenge is "a book with more than 500 pages", which can take a while to read, and you may need to get onto that sooner rather than later. Now, you can't narrow your search in our systems to the number of pages a book has, but it is possible to use One Search to see how many pages are in a book (even an eBook), as long as that information is in the system.
When you've searched for a book, click on the little magnifying glass with the word "Preview". One of the things you should see is the number of pages. This might not be available for all books, but it will help you discover that The Grapes of Wrath has 619 pages, while The Grapes of Math only has 337.
