Unfortunately I didn't enjoy Golden Son as my as Red Rising. The story starts well, setting off at a good pace, but it isn't long before things begin to drag a little. And then some more...until it became a hard slog to get through. I found the events described repetitive: fighting, pause for plot exposition, fighting, pause for exposition, fighting... etc. 
 However, I'm a compulsive completist so did push on to the third and final book in the series. 
 I've done a spoiler-free review of the whole Red Rising Trilogy on my book blog.
