A trash bag full of hacked-off body parts. A man thrown from a moving car. A young gang member, brutally tortured and killed. A yellow, shriveled corpse, oozing something other than blood. Besides the fact that the C.S.U. found them all on the same day, it seems the cases have nothing to do with each other. But, when interwoven, they point to a plot more elaborate, and more sinister, than anything C.S.U. newbie Madison Cross has ever seen. To investigate, she’ll have to descend into Philly’s seedy underworld of gang brutality—and then rise to the highest echelon of organized crime. But members of both hope to see her eliminated, once and for all.
