I was deeply impressed by the way the author presented the推理 (reasoning) from a slightly different angle and the well-thought-out logic, and I finished reading it in one go. I was on the edge of my seat until the very last line. Please, those who haven't read it yet, enjoy! I read it once and then stored it on my bookshelf. There are no markings or tears inside. (Please also refer to the images for the condition.) Returns/refunds are not accepted to prevent switching of items. Although it is unused, please understand that it is a used item before purchasing. I do not recommend purchasing if you are concerned. - Title: Ark - Author: Haruo Yugi - Publisher: Kodansha Bunko - Price: 913 yen (tax included) - ISBN: 9784065358542
