One of Milligan's finest works is collected and back in print today! The Extremist, with art by Ted McKeever, is a twisted story about choice and freedom set against a fetishistic, psychosexual backdrop.
Go out to your local comics shop and grab a copy. It's an excellent read and a worthy purchase--all four issues for only 8 bucks. Go, go!
