Twitter: https://twitter.com/loversdiction: Levithan's Twitter account, which both supports and extends his book The Lover's Dictionary (2011): "THE LOVER'S DICTIONARY is the story of a relationship told in the form of dictionary entries. Please buy the book from a local store; this is the unabridgement."
Publishers Weekly Review of The Realm of Possibility, Levithan's 2004 project--essentially a novel made up of poems, each reflecting the life of a different teen. A required text in several sections of Stretch Composition in recent years.
