Camouflage

Summary

Joe Haldeman traces two immortal shapeshifting aliens, one a curious changeling and the other a violent chameleon, who have lived hidden on Earth for millennia and are drawn toward a mysterious artifact recovered from the deep ocean. The narrative moves across decades and identities as the two beings circle one another and human investigators close in. Haldeman uses the premise to probe what makes us human and the meaning of empathy.
