In Edge of the Orison the visionary Iain Sinclair walks in the steps of poet John Clare

In 1841 the poet John Clare fled an asylum in Epping Forest and walked eighty miles to his home in Northborough. He was searching for his lost love, Mary Joyce - a woman three years dead ...

In 2000 Iain Sinclair set out to recreate Clare's walk away from madness. He wanted to understand his bond with the poet and escape the gravity of his London obsessions. Accompanied on this journey by his wife Anna (who shares a connection with Clare), the artist Brian Catling and magus Alan Moore - as well as a host of literary ghosts, both visionary and romantic - Sinclair's quest for Clare becomes an investigation into madness, sanity and the nature of the poet's muse.

'Brilliant . . . amusing, alarming and poignant. An elegy for an already lost English landscape. Magnificent and urgent'Robert Macfarlane, Times Literary Supplement

'A sensitive,beautifully rendered portrait . . . a feast, a riddle, a slowly unravelling conundrum . . . a love-letter to British Romanticism'Independent

'Sinclair walks every inch of his wonderful novels and psychogeographies, pacing out huge word-courses like an architect laying out a city on an empty plain'J. G. Ballard, Observer
