** Actually 4.5 stars*** 
 This story was a bit Frankenstein meets Lord of the Flies meets The Hunger Games with a good helping of Roman mythology. Its a very interesting combination. 
 This book was somewhat slow to get going. I would say for the first 1/3 I was having a hard time paying attention because it wasn't very interesting yet. (Which is the only reason I'm taking off half a star) However, the second 2/3 were amazing. Such a great build! This book really built stream towards the conclusion. (view spoiler)[O my gosh... When reaper killed Apollo and took Olympus! Soooooo good! (hide spoiler)] 
 I'm really looking forward to Golden Son. I was to see more of Reaper, Sevro, Mustang, Roque, and the Howlers. I hope they make appearances. :)
