When one of the greatest betrayals the Nephilim have ever known is revealed, Clary, Jace, Isabelle, Simon, and Alec must flee – even if their journey takes them deep into the demon realms, where no Shadowhunter has set foot before, and from which no human being has ever returned…
Love will be sacrificed and lives lost in the terrible battle for the fate of the word in the thrilling final installment of the classic urban fantasy series The Mortal Instruments!1
