Phenomenal. Ichor is now my new favourite book! It has set the bar.
"Percy Jackson for adults" pretty much sums it up! 
 
Ichor ticked all the boxes for a step into an Ancient Greek Mythology telling. There are some dark elements to the story so please read the TWs if you need to.
Trish really did a service to many Gods and Goddesses that aren't as commonly named in other Mythological stories and did not disappoint with the way she blended her knowledge into her story. The chapters are relatively short and all flow easily into each other. 
 
Humans when they turn 18, stand before the Gods who rule their dystopian earth as property to be claimed through battles to do whatever they please with. I was HOOKED from chapter 1. I was gasping, kicking my feet, crying and shaking my Kobo around the entire time. The writing style and language used is very much in line with what one would expect.
