I really did try to enjoy Hades. I put aside whatever thoughts I had of Halo and tried to read this novel from fresh eyes. But really, I don't think truly liking this series is possible anymore. 
 Bethany is, I believe, not an angel but a teenage girl masquerading as an angel. Honestly, I'm sure it was an ingenious idea to have an angel so young and naive that she becomes likable to those around her. Unfortunately, she didn't have that effect on me. I don't believe angels actually behave the way they do in the series, I'm more on the side that angels are warriors of God, but really, Bethany takes the cake. 
 She's so naive, too trusting of strangers, leaves her friends in the lurch, and she comes off as too preachy. Lines such as "the purpose of sex is to create life" are commonplace. Disregarding whatever personal opinion I have on such matters, such lines from a book is only going to turn off readers. Oh, oh, and her relationship with Xavier? Still very unhealthy. The fact that they can fall in love and remain in love given their interactions and how they met, etc, is not only amazing, it requires a genius to understand it. The ending of Hades? Can't say I didn't see that one coming but WTF?! 
 HADES IS ALSO NOT HELL. Hades is also known as the Underworld. This is not Hell. They are two completely different entities. As a fan of Greek mythology, I was deeply offended and disappointed too. Adornetto's idea of Hades/Hell is really weird as well, in the sense that it's full of preachy ideas, of things NOT to do while on earth if you don't wanna end up in hell after you're dead. 
 Another BIG disappointment was the Lake of Dreams plot device. Since Bethany has been kidnapped, no one is there to narrate what's going on Earth so with the help of the Lake of Dreams, (view spoiler)[she's about to astral-project and see what's happening in the real world to push the story along (hide spoiler)]. Let me tell you, it was so boring. Also, in all my readings of Greek mythology, I've never read anything about the Lake of Dreams, let alone (view spoiler)[the whole astral-projection shit (hide spoiler)]. 
 So really, I don't see why I should continue with the series except well, it's fun to see how everything unfolds.
