There is a side actually Hunger Games, but not so much in the story itself, rather in the character of Tris, his manner, his tremors and questioning, his weaknesses and strengths, each evoking Katniss page ...
I ordered the following books, and the fourth volume, 'Four', was released in July 2014, which promises great reading this summer!
