Glass is the second novel in the verse novel series Crank by Ellen Hopkins, published in August 2007. The hardcover edition was first released, and the softcover was released on April 7, 2009. The third book of the series, Fallout, was published in 2010. Like the previous novel in the series, Glass has been the subject of controversy, with the book being partially responsible for a public appearance by Hopkins getting cancelled due to parental complaints.
