Half the time, Maya looks like a mountain lion. On a space station over the planet Elsajh, she’s mistaken for a local shapeshifter, and she chooses to impersonate her alien look-alike. She stops an invasion and becomes a populist hero. That seems great, but her true identity stirs trouble for and her doppelganger.
