Apart from the incessant stalking, it is the conditionals--the contingencies--that most frustrate Joe, a scientific journalist. If only he and Clarissa had gone straight home from the airport... If only the wind hadn't picked up... If only he had saved Jed's 29 messages in a single day... Ian McEwan has long been a poet of the arbitrary nightmare, his characters ineluctably swept up in others' fantasies, skidding into deepening violence, and--worst of all--becoming strangers to those who love them. Even his prose itself is a masterful and methodical exercise in de-familiarisation. But Enduring Love and its underrated predecessor, Black Dogs, are also meditations on knowledge and perception as well as brilliant manipulations of our own expectations. By the novel's end, you will be surprisingly unafraid of hot-air balloons, but you won't be too keen on looking a stranger in the eye. --Alex Freeman
