Declare by Tim PowersRead about another book on the list.
The less known about a Tim Powers novel going in, the better, so may I suggest stopping now and reading this book if you haven’t already? Declare is a tale of twentieth century weirdness that follows a world of secret knowledge struggling to reinvent itself in the face of deeper and more secret knowledge. Catching hosts of strange-but-true details of history in the net of its plot, Declare melds the plausibly deniable symbolism and grandiose, grotesque schemes of magic and espionage.
