Writhe

Garrett was an ordinary New Yorker, appeasing annoying neighbors and paying over-inflated rent for a dumpy apartment in Hell's Kitchen. That is...
Until the larvae hatched.
As the end of the year draws near, Garrett unleashes his violent wrath upon the city of Manhattan. NYPD officers Luca Han and Mel Tredo are on a mission to find the depraved lunatic before he can kill again. Can they capture the homicidal madman in the surging sea of potential victims before the ball drops in Times Square?
Writhe is a hyper-violent novella of extreme horror from twisted sisters Erica Summers (Vanity Kills, Bad God's Tower, Mantis) and H. M. Wohl (From Ashes, Desdemona in Embers)
