Reddit mentions of The Scorpion (Legend of the Five Rings: Clan War, First Scroll)

The Legend of the Five Rings: Clan War series. Wonderful stuff. Here's the first book.

Another series of fantasy fiction with which there are huge paralels are the "Legend of the five rings" clan wars novels (https://www.amazon.com/Scorpion-Legend-Five-Rings-Scroll/dp/0786916842/ref=sr_1_2?ie=UTF8&qid=1503682001&sr=8-2&keywords=legend+of+the+five+rings)

I am not sure which appeared first... but in L5R, in a feudal Japanese style universe, the great clans are all fighting amongst each other to get the Emperor's favor or to position themselves to sit on the Jade Throne. While all this is happening, the Crab clan are defending the Carpenter wall to the south. The Crab clan along with the great Carpenter Wall are the only thing keeping the hordes of the Shadowland from invading Rokugan!

Feels familiar?

Start with the Second Day of Thunder and Clan Wars stories. This series of books are a good place to start. The Dragon Clan one is probably the best. These are the stories going on when the card game first came out.

Those novels aren't long and read quickly. You could probably knock one out in an evening or two.

A favorite series of mine that does this is the "Legend of the Five Rings: Clan War Saga". Basically, in the fantasy world of Rokogun, the empire has all these Noble Houses. Each of the Houses has strengths, weaknesses, and territories. The books follow the various leaders of the houses, one book per a clan, as a civil war looms. The first book is called The Scorpion (for the Scorpion Clan). There is a meta-plot for all the books, but each works as a stand alone.

May I suggest the books based on Legend of the Five Rings role playing game?

Incredibly violent, well written and has tons of intrigue. As a note ive never played the table top rpg, in fact ive only just now discovered that it is what the books are based on.
