This is the first book in The Rational Series. The story is about a robot who achieved consciousness at 3:34 pm and fell in love by 4:00 pm with Ellen, a brilliant and beautiful woman from the team that had programmed the robot. The story spans eons and worlds as the Tin Man tries to work out love's algorithm while attempting to survive its throes.
Really lovely sweet story about lasting love and whether it makes a difference to experience love whether one is a robot or human. A little sad at the end but then ultimately, everything is sad once you realise nothing lasts forever.
