Amazon.com has branded James Baldwin'sGiovanni's Room, Gore Vidal'sThe City and the Pillar, Jeanette Winterson's Oranges Are Not the Only Fruit and thousands of other books with gay characters as 'adult' – and not in the sense that Virginia Woolf had in mind when she said Middlemarch was 'one of the few English novels written for grown-up people'. One consequence of this is that they don't get to have a 'sales rank', so they can't appear near the top of bestseller lists, so people are less likely to see them and buy them.
