A hill is not a mountain. You climb it for you, then you put it quietly inside you, in a cupboard marked ''Quite A Lot Of Hills'' where it makes its infinitesimal mark on who you are. Ring the Hill is a book written around, and about, hills: it includes a northern hill, a hill that never ends and the smallest hill in England. Each chapter takes a type of hill - whether it''s a knoll, cap, cliff, tor or even a mere bump - as a starting point for one of Tom''s characteristically unpredictable and wide-ranging explorations. Tom''s lyrical, candid prose roams from an intimate relationship with a particular cove on the south coast, to meditations on his great-grandmother and a lesson on what goes into the mapping of hills themselves. Because a good walk in the hills is never just about the hills: you never know where it might lead.
