From the publisher's website: It's the free Spirit of the Century adventure tie-in to Chuck Wendig's Dinocalypse Now! While the heroes of the novel unravel the mystery of the cross-time invasion, another group of centurions, stranded in Los Angeles and on the run from psychosaurs, must join forces and save the city from dinosaurs, evil apes, and conniving neanderthals. From dizzying roof-top heights, to the depths of the Shadow Baron's criminal empire, this town's gone to Hell -- and only a weakened Century Club has a chance of stopping it all!
