Amazon.com description: Product Description: Salvage and Demolition, the astonishing new 21,000 word novella by Tim Powers, begins when Richard Blanzac, a San Francisco-based rare book dealer, opens a box of consignment items and encounters the unexpected. There, among an assortment of literary rarities, he discovers a manuscript in verse, an Ace Double Novel, and a scattering of very old cigarette butts. These commonplace objects serve as catalysts for an extraordinary--and unpredictable--adventure.

Without warning, Blanzac finds himself traversing a 'circle of discontinuity' that leads from the present day to the San Francisco of 1957. Caught up in that circle are an ancient Sumerian deity, a forgotten Beat-era poet named Sophie Greenwald, and an apocalyptic cult in search of the key to absolute non-existence. With unobtrusive artistry, Powers weaves these elements into something strange and utterly compelling. The resulting story is at once a romance, a thriller, and the kind of intricately constructed time travel story that only the author of The Anubis Gates--that quintessential time travel classic--could have written. Ingenious, affecting, and endlessly inventive, Salvage and Demoliton is a compact gem from the pen of a modern master, a man whose singular creations never fail to dazzle and delight.
