Owarimonogatari : End Tale

From the best selling novel series comes the latest book of the final season of the Monogatari Series.

Before we witness the series’ climactic showdown in the third volume of the End Tale—each part of which forms its own cohesive whole—narrator Araragi wrestles with a crucial bit of history that had turned him into the loner we met at the very beginning, who opined that friendships only lowered his
intensity as a human.
What initiates his pilgrim’s progress of a reckoning is his first encounter, at school, with the mysterious freshman Ogi Oshino, self-described niece of the equally enigmatic aberration expert Mèmè, and the book’s opening chapter is a harrowing standalone novella of a who-dunit involving a locked room of sorts.
Our increasingly well-adjusted hero kept on beingdecent at one thing even when he was just hanging on, but this forte, an unlikely aptitude for math, of all things, becomes the focus of a cheating scandal and a web of recollections that forces him to come to terms with, what do you know, his capacity to connect to people.

There are few authors in Japan who have reached the heights of success as NisiOisin. Born in 1981, Nisio dropped out of Ritsumeikan University in Kyoto, to pursue a career in story-telling. Initially he had ambitions to be a comic artist, but when he realized his art was not up to snuff, he began to focus on his writing, eventually winning the 23rd Mephisto Prize, for Decapitation recognizing his talents as a mystery writer, at the age of 20. Since his debut in 2002 Nisio has penned more than 50 novels and a number of comics. And he has quickly become one of Japan's top selling author's in recent memory with more than 5 million units sold since 2009. In 2014, as in 2012, he was the top selling author in Japan (outselling Haruki Murakami by more than half a million units).

Nishio's works often cover themes of youth, but are framed in genres that are familiar to the masses. His works tend to mix mystery with comedy and touches or romance and/or the supernatural. He is a modern author in every sense, sometimes even experiementing with the Japanese language itself. Many of his works have been adapted into animated television series and films. His best known works are the Monogatari series and Katanagatari.
