The award-winning, bittersweet sci-fi tale of a mysterious tunnel, time travel, and young summer love that inspired an anime film. Don’t miss the manga adaptation and the light novel Wait For Me Yesterday in Spring (by the same creators), both also from Seven Seas! One summer morning before school, Kaoru hears an unsettling rumor—of a mysterious tunnel that can grant any wish to those who enter it, but ages them dramatically in exchange. At first, he writes it off as nothing more than an urban legend, but that very night, he happens upon the selfsame passage: the Urashima Tunnel. As he stands before its gaping maw, a thought occurs to him—if this tunnel truly does have the power to grant any wish, could he use it to bring his younger sister back from her untimely.

This coming-of-age story explores themes of grief, sacrifice, love, and the bittersweet nature of time itself. Perfect for fans of Your Name, I Want to Eat Your Pancreas, or Weathering With You, this emotional journey will leave readers moved and introspective.
