The Tunnel to Summer, the Exit of Goodbyes
Also known as: Natsu e no Tunnel, Sayonara no Deguchi, 夏へのトンネル、さよならの出口, Tunnel to Summer, Goodbye Exit, คำจากลาของคิมหันต์ ณ ปลายอุโมงค์
by Mei Hachimoku
Kaoru Touno heard a rumor: The laws of space and time mean nothing to the Urashima Tunnel. If you find it, walk through and you’ll find your heart’s desire on the other side…in exchange for years of your own life. On the night Kaoru just so happens to find himself standing in front of a tunnel that looks suspiciously like the one the rumor describes, he finds himself thinking of Karen, the sister he lost in an accident five years ago. To Kaoru’s surprise, he’s been followed by the new transfer student Anzu Hanashiro, who promises to help him experiment with the mysterious tunnel–but what does she want from Kaoru in exchange? And what will he have left to give, after the tunnel’s done with him? (Source: Seven Seas Entertainment, edited)

Read the full take
Kaoru Touno heard a rumour: the laws of space and time mean nothing to the Urashima Tunnel. If you find it and walk through, you will find what you have been looking for. That premise is a neat, tightly constructed hook, and the novel uses it as a structure for both mystery and grief.The strength is the construction. The narrative is precise, and each piece of the time-slip logic earns its place. The emotional arc builds quietly, and the reveals are satisfying without undermining the story's sincerity.The weaknesses are clear. The book is short, which leaves some threads brief. Readers who need every rule explained may find the supernatural premise accepted rather than argued.Recommended for readers who enjoy compact, emotionally precise time-slip stories. Expect a tight, moving read.
