Possession / by A. S. Byatt

Vintage, 1991. Trade pb. VG. 

Winner of England’s Booker Prize and a literary sensation, Possession traces the lives of a pair of young academics as they uncover a clandestine relationship between two long-dead Victorian poets. As they unearth their letters, journals, and poems, and track their movements from London to Yorkshire—from spiritualist séances to the fairy-haunted far west of Brittany—what emerges is an extraordinary counterpoint of passions and ideas.
