After I took off the training wheels and started reading "big-girl" books, I kicked YA to the curb. However, Cassandra Clare's The Mortal Instruments series has always had a special place on my bookshelf. After I finished the first three books in the series a few summers ago, I immediately picked up City of Bones and read them all over again. Even the Twilight books don't have the distinction of earning an immediate re-read!
City of Lost Souls (The Mortal Instruments #5) is scheduled to be released on May 8th, 2012.
