I'll be honest. I started reading this series because a library I used to go to a lot had a shelf of free books you could take home and keep. I went through that shelf and took books that looked my genre type and had a bunch. I brought home volumes 1-4&6 of this series. And so far it's been mind blowing to read, when I finished volume 4 I rushed to purchase volume 5 and I look extremely forward to purchasing the rest of the series in the future.
