So I battled my way through the books this far, then gave up. I hate leaving books/stories unfinished, so I kept going because I was curious to know what was going to happen, but it's just not worth it.
The premise is interesting, and the first book was OK, but there has been no real structure to the storyline over these seven books. Unlike J.K. Rowling who, whilst writing a long series, clearly had a structure in mind, it's like the authors are just making it up as they go, randomly introducing new concepts which should at least have been alluded to before to keep the story going, and constantly changing their minds about where they want it to go. (Erik? Heath? Loren? Stark? Kalona?) They keep on changing characters', well, characters, seemingly hoping their readers aren't bright enough to question it. They get bored with one boyfriend and move to another, hastily throwing in a comment about how the perfect guy actually was horrible the whole time (which isn't believable, as we'd never seen anything to indicate it until then). This series is dragging much too long. (What are we on, book 11, 12 at this point?)
I admit though that I liked the change in Aphrodite - in fiction, the snobby 'cheerleader' type often just stays that way, as they are there solely to make the protagnist's life hard. Aphrodite is my favourite character, because although she's a bit of a b****, she knows it, unlike Zoey who seems to think flowers should bloom in the dust at her feet. Actually, that's not quite true; it seems like the *authors* want you to think they should, that she's perfect despite her faults. But no amount of telling me that Zoey is special and chosen can erase the fact that she cheats on her boyfriend and then gets all mad when *he's* angry about it. Yes, she says it's hard for her when he rubs it in because she's agonised over it for ages, constantly blaming herself, but we never really saw much agonising, and telling us that she did in the face of all the evidence just makes me think she doesn't actually know what remorse is.
Zoey whines over how hard everything is and how she can't do it, while you sit there shouting 'use the elements!' And after half a book of 'oh, what can I do?' the solution is obvious and much too easy -- she just has to follow her gut/ask Nyx/invoke the elements. At the same time, the authors introduce useful stuff and then never refer to it again (Stevie Rae climbing up walls -- v. useful, and never mentioned again).
Also, what is with the horrible parents in fiction (especially unpublished) nowadays? Quite apart from coming across as the author's attack on a religion by portraying its followers as inevitably bigoted and judgemental, it's pretty unrealistic. It's as if a teenager wrote it, wanting to vent, and 'making it ok' by portraying the parents as unreasonable sadists, so it's fine to hate them.
Add the typos the editor missed (silver/sliver), and I don't know why this was published in the first place. Apologies for being so harsh but this is the standard I have come to expect from self-published works online, not ones which actually have been published.
