On a snowy night in the winter of 1861, the first after Hangzhou fell, the books of the Wenlan Pavilion Library were treated as wastepaper and carted off to a paper mill.
Xi Wangye, an apprentice papermaker, pulled a page from the Complete Library of the Four Treasuries out of a boiling vat of pulp. As water washed over the old ink, he heard half a sentence spoken by a proofreader long dead, as well as the whereabouts of thirty-six chests of books secretly removed from Gushan.
On one side were ancient books that could be traded for life-saving rice; on the other was a world of words on paper that could vanish at any moment. Following scraps of pages, collector's seals, and patches of paper, Xi Wangye and Ye Hengjun, the daughter of a former library proofreader, searched postwar Hangzhou for the missing books. They saw pages used to wrap medicine, paper walls, and line coffins. They saw someone break up an entire book to save ten families, and someone else spend their entire fortune buying scattered pages back one by one. But the closer they came to the underwater catalogue, the more they realized that the calamity at Wenlan Pavilion had not begun when the city fell. A theft and substitution scheme had been going on for decades, mixing genuine volumes with copies and forgeries.
Xi Wangye could hear the “old voices” left behind in the paper, but every page he heard clearly cost him a piece of his own voice. Only when he finally heard the warning his father had left in a book did he understand that what he needed to save was never just a library. It was also the story of how this city had lived, how it remembered, and how it passed its memories on to those who came after.
