My Calculating God, the beloved Hugo Award-nominated novel about the conflict between science and religion — perfect for fans of Mary Doria Russell’s The Sparrow and Carl Sagan’s Contact — has a new 25th-anniversary edition (in hardcovertrade paperback, and ebook!) with spectacular new cover art by Lui Junwei.

An alien walks into Toronto’s Royal Ontario Museum and asks to see a paleontologist. Dinosaur expert Tom Jericho is stunned to learn that many worlds experienced the same five great mass extinction events as Earth did, and that the aliens believe this proves God tampers with the evolution of life. As Tom faces his own mortality, will his life-long atheism be shaken by these revelations?

Praise for Calculating God:

  • “Spectacular; this is unusually thoughtful SF.” —Publishers Weekly
  • “The premise is astounding. A fine read; an intellectual thriller with real bite.” —Edmonton Journal
  • “The best science fiction novel of the year.” —Denver Rocky Mountain News
  • “An engrossing and nuanced novel, full of food for thought and meat for meditation, the sort of epistemological gavotte that reminds us why God invented science fiction in the first place.” —James Morrowauthor of Towing Jehovah
  • “Sawyer ends with grandeur worthy of Arthur C. Clarke.” —The Denver Post
  • “An action-packed yet highly philosophical, theological, and ethical story. Well-melded into the fast-paced plot, a wonderful dialogue goes on over the God question and over right, wrong, and the purpose of life. It’s guaranteed to expand the minds of believers and non-believers alike.” —Tom Harpur in The Toronto Star
  • “Sawyer once again demonstrates his wild talent for innovative, iconoclastic storytelling as he relates a thought-provoking, sobering, yet wryly compassionate tale of one man’s discovery of timelessness even as his own time is running out.” —Library Journal
  • “Exciting and emotional. Sawyer smoothly combines ethical questions and comical dialogue in a highly absorbing tale.” —Booklist
  • Calculating God is the most captivating work of science fiction I’ve read since Carl Sagan’s Contact.” —Victoria Times Colonist
