    Miles Bennell discovered an insidious, horrifying plot.

    The work of English clergyman, educator and Shakespearean scholar Edwin A. Abbott (1838-1926), it describes the journeys of A. Square [sic – ed.], a mathematician and resident of the two-dimensional Flatland, where women-thin, straight lines-are the lowliest of shapes, and where men may have any number of sides, depending on their social status.Through strange occurrences that bring him into contact with a host of geometric forms, Square has adventures in Spaceland (three dimensions), Lineland (one dimension) and Pointland (no dimensions) and ultimately entertains thoughts of visiting a land of four dimensions—a revolutionary idea for which he is returned to his two-dimensional world. Charmingly illustrated by the author, Flatland is not only fascinating reading, it is still a first-rate fictional introduction to the concept of the multiple dimensions of space.

    It is said a race of shapeshifters once lived here, only to perish when men came. But one man believes they can still be found, somewhere in the back of the beyond.In The Fifth Head of Cerberus, Wolfe skillfully interweaves three bizarre tales to create a mesmerizing pattern: the harrowing account of the son of a mad genius who discovers his hideous heritage; a young man's mythic dreamquest for his darker half; the bizarre chronicle of a scientists' nightmarish imprisonment.

And some sleep in beds with lids.Now the house is being readied in anticipation of the gala homecoming that will gather together the farflung branches of this odd and remarkable family. In the past-midnight stillness can be detected the soft fluttering of Uncle Einars wings. From her realm of sleep, Cecy, the fairest and most special daughter, can feel the approach of many a welcome being -- shapeshifter, telepath, somnambulist, vampire -- as she flies high in the consciousness of bird and bat.But in the midst of eager anticipation, a sense of doom pervades. For the world is changing. And death, no stranger, will always shadow this most singular family: Father, arisen from the Earth; Mother, who never sleeps but dreams; A Thousand Times Great Grandmére; Grandfather, who keeps the wildness of youth between his ears.And the boy who, more than anyone, carries the burden of time on his shoulders: Timothy, the sad and different foundling son who must share it all, remember, and tell...and who, alone out of all of them, must one day age and wither and die.By turns lyrical, wistful, poignant, and chilling, From the Dust Returned is the long-awaited new novel by the peerless Ray Bradbury -- a book that will surely be numbered among his most enduring masterworks.
