"Rife with tension and unexpected twists, this conceptually-expansive science-fiction novel relies strongly on the human element to grab—and hold—readers' sympathies. -The Horn Book "With the same enthralling, cinematic pacing he used in LAST DAY ON MARS (2017), Emerson unspools nail biting suspense in this sequel, all while employing a solid grasp of real science and paying homage to classic sci-fi stories. Through all the engrossing sci-fi action, however, Emerson keeps the plot solidly grounded in the characters, who are real and complex. -Booklist FULL REVIEW
"Arcs of emotional tension braid through outer-space flying and fighting scenes, various aliens, jolts of puzzle-mystery time travel, and science/philosophy ("Now and then are constraints of three-dimensional beings.") Thrills, violence, time/space questions, and some contemplation about colonization make for action on the thoughtful side." -Kirkus FULL REVIEW
"Well written and exciting..." -School Library Journal
