This stimulating and bruising sequel to Scottish author Duncan's neo-Joycean Vellum
(2006) projects the endless battle between good and evil onto a kaleidoscopic multitude of parallel alternative realities. Duncan's debut introduced bionanotech-enhanced humans, who clashed with ordinary humans in a 2017 apocalypse. The Carter family of Glasgow guarded the God-commissioned titular Book, but now the scribe and angel Metatron has hidden the Book somewhere in the infinite folds of a realm called the Vellum and is preparing to die. Meanwhile, a host of eerie characters, including foul-mouthed Jack "Flash" Carter, Puck-figure Thomas Messenger and Jack's shrink, Guy Renard Carter, search for the Book. Full of riffs on myths from throughout human history as well as allusions to Euripides'Bacchae
, this enormous, stinging, poignant hymn engenders a terrible beauty all its own. (Feb.)
