Professor Ishi Banesa and his grandmother, passing as humans, are the last descendants of those who escaped runaway warming on Venus millions of years ago. When an ancient spaceship is uncovered Ishi agonizes over being outed, frets his grad student’s budding love for him will be quashed, and worries his life’s mission to save Earth from runaway warming will be derailed. But when “Space Alien Vigilantes” start killing people mistaken for space aliens, Ishi must overcome the greatest fear of his life and reveal his identity.
