Londoner Richard Mayhew and his ice-princess fiancee are hurrying to dinner with her media-tycoon boss when Richard spies a young woman lying dirty and bleeding in the street. Uncharacteristically not thinking twice, he picks the apparent beggar up and, leaving his intended on the spot, carries her to his apartment to recuperate. Next morning, two eerie men are at Richard's door. They are looking for the young woman, who is in the bathroom when they arrive. Over Richard's protests, they barge in and search the place, but the girl is nowhere to be found. After they leave, however, she shows up at Richard's elbow in the kitchen. Strange. But humdrum compared to the quest that Door (the young woman) enlists Richard to undertake with her in London Below, a subterranean city made up of long-forgotten parts of historic London and populated by people who "fell through the cracks," as Richard discovers he has shortly after Door first leaves him, and friends fail to recognize him, while strangers don't even seem to see him. The millions who know The Sandman, the spectacularly successful graphic novel series Gaiman writes, will have a jump start over other fantasy fans at conjuring the ambience of his London Below, but by no means should those others fail to make the setting's acquaintance. It is an Oz overrun by maniacs and monsters, and it becomes a Shangri-La for Richard. Excellent escapist fare.

Some of the best pure storytelling around these days is being produced in the critically suspect genre of fantasy, and this exuberantly inventive first full-length novel, by the co-creator of the graphic series The Sandman (1996), is a state-of-the-art example. The protagonist, determinedly unheroic Richard Mayhew, is a young man up from the provinces and living in London, where he has found both job success and a lissome fiancCe, Jessica. Soon, however, Richard meets a mysterious old woman who prophesies he'll embark on an adventure that starts with doors.'' Sure enough, his fate becomes entwined with that of a beautiful waiflike girl who calls herself Door, and who is in flight from a pair of ageless hired assassins and in pursuit of the reason behind the murder of her family. Suddenly wrenched away from his quotidian life (people can no longer see or hear him), Richard follows Door underground to an alternativeLondon Below,'' where ``people who have fallen through the cracks'' live in a rigidly stratified mock-feudal society that parallels that of London Above. A parade of instructors and guides brings Richard and Door ever closer to understanding why her father was marked for death by the rulers of London Below, and prepares Richard to do battle with the (wonderfully loathsome) Great Beast of London. Altogether, Gaiman's story ending is both a terrific surprise and a perfectly logical culmination of Richard's journey into the darkest recesses of his civilization and himself. The novel is consistently witty, suspenseful, and hair-raisingly imaginative in its contemporary transpositions of familiar folk and mythic materials (one can read Neverwhere as a postmodernist punk Faerie Queene). Readers who've enjoyed the fantasy work of Tim Powers and William Browning Spencer won't want to miss this one. And, yes, Virginia, there really are alligators in those sewers—and Gaiman makes you believe it. (First printing of 125,000)"
