From The SF Gateway, the most comprehensive digital library of classic SFF titles ever assembled, comes an ideal sample introduction to Joe Haldeman, one of SF's most decorated authors. Haldeman is best known for the Hugo and Nebula Award-winning The Forever War, a novel which draws on his experience as a combat engineer in Vietnam, where he was wounded and earned a Purple Heart. This omnibus collects the Carmen Dula sequence comprising Marsbound, Starbound and Earthbound, which chart humanity's response to the challenge of alien contact.
