A children’s author and poet who had become a keen amateur photographer, Peters watched the butterflies and idly wondered if he could capture them in flight. It swiftly became an obsession as he recovered from a successful operation to remove the cancer. In recent summers, he has travelled the length and breadth of Britain to photograph all 58 native species of butterfly. Now the fruits of those summers have been published in a beautiful new book.

彼得斯是一位儿童作家和诗人，后来成了一名热心的业余摄影师。他看着那些蝴蝶，随意地想自己能否拍下它们飞行的样子。在成功切除癌症的手术后康复期间，这个念头很快变成了一种痴迷。最近几个夏天，他走遍英国各地，拍摄了全部58种本土蝴蝶。如今，这几个夏天的成果已汇编成一本精美的新书出版。

这场斗争在许多不同层面上展开：拿破仑的法国军队与愤怒的当地居民之间；一心想加剧皇帝困境的英国人与从巴黎派来试图遏制他们的元帅们之间；科学与任人唯贤的新势力和保守主义与门第出身的旧势力之间。
