I loved the first 2 books. I loved only part of one sub-plot of this book- Dean, Austin and the mummy, and that isn't enough to love the whole book. Claire's ok in parts, but I didn't really see why she had to do the beach thing and the Egyptian otherworld thing. Lance was over-done and I didn't catch the Australian jokes.
I didn't mind the lesbian thingy - at least I understood that part. Most of the time I just couldn't figure out what was going on, especially since Sam and Austin were separated from Claire and Diana so there were 5 threads to follow, none of which seemed to converge much.
Things made a twisted kind of sense in the 1st 2 books, maybe because the plots were simpler. Some of those rules are also found in this book, but somehow I couldn't follow out how the mall(s) worked in this story.
And while it's Diana's story, she doesn't come across as the heroine. I was hoping that Diana would find her feet as a keeper. She still comes across as a nasty immature and (sigh) impotent person. I need heroines I can like.
Ms Huff is definitely capable of better. I'd buy the next book in the series if it's about Claire. Even if it's a better Diana in a sequel, I shudder to think of wading through all that teen-speak. It's hard enough to follow as it is, and it'll only become dated.
