A stack of books that were either never finished, never published, or were destroyed.
Pratchett’s unfinished works were run over by a steamroller as per his wishes, Waugh set fire to his manuscript, Sappho’s poetry was burned by order of the Pope and Lady Wortley Montagu’s daughter threw her journals in the fire for being too incendiary, ironically. The others were either started or planned out but never completed.
