How is London an important setting in the novel, The First Fifteen Lives of Harry August?

London is the location Harry escapes to when he leaves the North East. It provides sanctuary to him: it is the first location where he encounters the Cronus Club and always the first destination he heads to when escaping his childhood in the North East. When Harry visits London in his thirteenth life he discovers that the Cronus Club there has been destroyed. When London fails to offer him his usual sanctuary this is symbolic of the fact that Harry is now alone and must act without any outside support.
