‼️SEARCHING FOR‼️ Mortal Instruments Series

I'm looking for all 6 books from the Mortal Instruments series, preferably hardback, and to not have names written in them permanently like with pen. Would pay up to $60 the price is negotiable, would pay $30ish for series in paperback. City of Bones, City of Ashes, City of Glass, City of Fallen Angels, City of Lost Souls, City of Heavenly Fire.
