It started high, but then my interest waned as the book went on probably due to a number of events that seemed unnecessary against the overall story arc. There was no true suspense. Despite finding The Eye of Minds completely addictive, I found The Rule of Thoughts completely... the opposite. 
 This is definitely a case of Middle Book Syndrome, however I am anticipating The Game of Lives as conclusions and resolutions are what I look forward to experiencing the most. 
 (Cover love here though!)
