13 Days Left written by Rashid Sohail. A fast-paced magical world comes to an end. What I have taken from this book is even a short book could take you to a magical world, you don't always need a book of 300 pages only. Heister takes you on a ride in which he determines to defeat Zaar, the magic king & the devil. His friend Sam, teams up with him as they need to save their friends who are trapped by some spell of Zaar. There are a lot of adventurous happen to them that will make you feel like you're also travelling with them.
