Silk is back and badder than ever! Cindy Moon - the other victim of the radioactive spider that bit Peter Parker - has been working to find the missing members of her family since she escaped the bunker that was her home for so many years. But Silk's quest has taken her down a darker path than expected, and now she's in cahoots with the most ferocious feline in the Marvel Universe: the Black Cat! But not everyone in the Cat's criminal crew is happy about the arrangement. Nor is a certain friendly neighborhood CEO of Parker Industries, and that will take Cindy into battle with Spider-Man and the Goblin King! What could have led her to this? And will she go so far that there is no redeeming the Sinister Silk?
