Now, I'm a big fan of Hoban's stuff. His early books had a density of imagery and linguistic abandon that marked him as an original. His later books, the 'London novels', are lighter in tone and substance, featuring recurrent characters. Suspiciously often they also feature old men fulfilling their sexual fantasies (RH is no spring chicken...). Nonetheless, they are usually very funny, sometimes affecting, and have anarchic and playful gimmicks by which they earn their keep.
In this case, Irving Goodman (an old man...) becomes infatuated with a long-dead 1950s Western starlet, and gets a technically-skilled acquaintance to bring her back to life (by means of some amiable hokum involving capturing her particles in a "suspension of disbelief"). Of course, she is reborn in black and white, and to fill herself with colour and life she must drink blood. Vampire cowgirl in London: all very Hoban.
Fun as this setup is, with a half-dozen narrative viewpoints, a pinball plot and a short text (160 pages with lots of white space), there isn't the depth here to work up any emotional involvement. There are perhaps notions of the tragedy of our animal condition, which leaves us prey to humiliating infatuations and indignities, diverting us from bettering our lives, or even accepting our lot. But these themes are hardly more than sketched out.
There's always much to enjoy in Hoban's books, but they are not all masterpieces like Riddley Walker, and Linger Awhile is pretty slight. (And the cover price of £10.99 on this slender paperback is taking the piss...)
