Loved this! The science fiction concept of time travel and being able to see/prevent/change the future was the backbone of this novel, but the human aspect and the relationships between the characters and how they changed throughout the story were the real meat of this novel. The science was presented in a sound and accurate manner (I think, not a quantum computing specialist or anything) that was also highly digestible and I never felt like I was missing any of the facts. Now granted, a lot of the science could have just been made up, but I still felt like I was able to follow along really easily. 

The characters were all multi-layered and believable and I felt like I was able to connect with and form an attachment to all of them as the story progressed. 

The concepts presented in this novel regarding the spiritual/ethical complications that come with being able to see/predict/change the future caused me to pause a few times and really think about what the right thing to do in some of these hypothetical situations would be. Very insightful novel and I really enjoyed it!
