World War One: 1914-1918 by Alan Cowsill and Lalit Kumar Sharma

Like World War Two, from the same publisher, this graphic novel mixes fact with fiction, large scale action with personal stories. It frames World War I with first person narration from an imaginary soldier named George Smith who enlists along with his brother in the British Army at the start of the war. Then it alternates George's story with stories of historical figures and from a broader point of view. It's an excellent and accessible look at the First World War. This is the first time I've actually understood the complex web of treaties and alliances that made Archduke Ferdinand's assassination the trigger to a world war.

Includes information on the animal soldiers and geographic scope of the war at the end of the book.
The book won Best Graphic Novel 2014 at the Comic Con India Awards.
