I have read all three in this collection - City of Bones, Ashes & Glass. Could not put them down at all! A fourth and final book is due to be released in 2011. Can't wait. These books have it all - demons, vampires, werewolves, warlocks, magic, romance, action, humour, sadness, shock twists, suspense. Everything. Wuold recommend them to anyone who is currently in the "Twilight Zone" !! I HOPE THAT ALL THE BOOKS ARE MADE INTO MOVIES. WHAT A TRILOGY! Don't hesitate. Order them today.
