Solar

Booker Prize–winner McEwan (On Chesil Beach ; Atonement ) once again deploys domestic strife to examine the currents of worldwide change. This time, McEwan shoots for the sun, with the promise of solar energy gradually legitimizing itself in the mind of Nobel Prize–winning physicist Michael Beard. While Bush v. Gore drags on across the Atlantic and Beard's fifth marriage dissolves in an adulterous haze, the waning laureate rides his reputation to a cushy position at a U.K. climate research center, where he is generally disdainful of his younger colleagues. Then, following an epiphany of sorts, Beard pins the accidental death of a rival scientist on his wife's lover and steals the other man's research. By 2009, Beard is in New Mexico, riding high on ill-gotten funding and patents and within sight of a curious redemption. Beard is a fascinatingly repulsive protagonist, but he can't sustain a novel broken up by fast-forwards (all of which require tedious backstories) and a stream of overwritten courtships. The scientific material is absorbing, but the interpersonal portions are much less so—troublesome, since McEwan seems to prefer the latter—making for an inconsistent novel that one finishes feeling unpleasantly glacial.
