《灰掐》由鴻鴻小說〈木馬〉、智海漫畫〈火車〉組合而成。
 
〈木馬〉是鴻鴻以台灣社會與政治現實為諷喻的魔幻作品，1998年發表，獲時報文學獎短篇小說評審獎；2007年，智海依此為靈感，畫出全新漫畫〈火車〉。兩人的創作循不同的迴路接電交匯，擦出奇異電光。
 
《灰掐》初版至今18年，期間譯有英、法、義、及芬蘭文版。2025年中文再版，載譽歸來。
 
The Train depicts a surreal train ride, where the train cars decouple and rejoin, and people lost and find one another. Only left with the protagonist waiting, endlessly, in the middle of nowhere and somewhere. Chihoi's dreamy narration and tour-de-force pecilscape, take inspirations from the award-winning short story Wooden Horse by Taiwanese writer / poet Hung Hung. The text and the comic adaptation are compiled together in this book in opposite directions. 
 
The book was first published in 2007 in Taiwan, and has been translated in English, French, Italian and Finnish. nos:books is honored to publish the new Chinese re-edition.
