Bullet Train (the book)

I recently watched Bullet Train on Netflix. And I loved it. Because it was a wacky action movie set in a train with just enough silliness and heart to be enjoyable. And in spite of the sillier elements, I did not feel like a complete braindead idiot watching it. I mean death and violence in a Japanese train, what's not to like? And I was happily surprised tosee that it was adapted from a novel by Kotaro Isaka. It is the second book of a series actually, so I am thinking, in spite of my TBR list, to buy it and maybe the first book as well. I read crime fiction from all around the world, so it would be nice to add Japan to the list of exotic crime location.
