Westerfeld is best known for the Uglies series, including the spin-off graphic novel series Shay's Story. Other novels of his include Afterworlds and, for adults, The Risen Empire and The Killing of Worlds, parts one and two of Succession.

Westerfeld began his career writing novels for adults but switched to YA literature with his Midnighters trilogy. He has written four YA novels that take place in New York City: Peeps, The Last Days, So Yesterday, and Afterworlds. While The Last Days is not a sequel to Peeps, it follows a group of different characters in the same setting. So Yesterday is not related to these novels but is often grouped with them because it is also set in New York City.

He has also written the Leviathan series, an alternate history trilogy set in World War I consisting of Leviathan, Behemoth and Goliath, plus its illustrated guide The Manual of Aeronautics.
