Reddit reviews Calculating God: A Novel

Robert J. Sawyer's Calculating God.

I'll throw in another vote for the Hunger Games trilogy, and the Sookie Stackhouse series isn't bad. If she enjoys supernatural fluff lit, then perhaps Patricia Briggs might be another good choice.

Some of my favourites:

• The Hummingbird's Daughter
  
• The Witch of Cologne
  
• Calculating God
  
• Running with Scissors: A Memoir

Quite the opposite. An admission that you are ignorant on a subject (or ignorant of answers,) does not preclude thoughtful examination. "Agnostic" just means, "without knowledge." People often self-identify as "agnostic" rather than "atheistic" when they don't have conclusive answers. Not having firm convictions leaves a lot of room for exploration and theorizing.

The SF novel Calculating God has a slightly different take on god in SF, for instance.
