"Labyrinth" is book 5 of Kat Richardson's Greywalker series, and I read it a couple of months ago now. I nearly decided not to write a blog post about it as it had been so long since I read it - this summer has been pretty hectic & I've been generating posts to write quicker than I can write them! (Which is a nice problem to have :) ). But I do want to make a few remarks for my own benefit even if I'm not sure how interesting or coherent they'll be for anyone else. And it's incredibly hard to say anything without spoilers for the previous books.
I thought when I started the series that these would be a never ending series of PI thrillers. That book 1 would be the origin story where Harper Blaine gets her ability to see and interact with the supernatural and then there'd be a bad-guy-of-the-book or mystery-of-the-book for each succeeding instalment. Instead it's become clear that there's an overarching story here, and I found out (after I read this book but before I wrote about it) that the ninth and final book has been published this summer. So that's reshaped how I think about the series a bit, and I think probably gives them more re-read value (and I'm annoyed now that I missed out on book 3 as it's more like missing a chapter of a novel rather than just an episode). I think I'll stick to using the library for now - but I should put them on the list to be bought & revisited later.
Plot wise, Harper is back on home ground here and we revisit some of the people and plot threads from book 1 but now Harper knows so much more than she did. It's become clear that what happened to Harper wasn't an accident, and that a lot of the people that seemed coincidentally linked to her in the first story actually had agendas of their own. Harper is also being changed by her increasingly deep connection to the Grey, and not in good ways. Over the last 4 books she's gradually opened up and made more friends & connections* and now the Grey is starting to take some of that away. I don't think this is going to turn out to be a tragedy overall, the tone so far hasn't felt like the sort of story where Harper could become evil and take over the world muahahahaha. But with 4 books left there's definitely time for these disturbing seeds to grow and it to get darker before pulling back at the end.
On a different note, after I read book 4 I wondered if the Egyptian vampires were a real legend - the author's note in this book says that they are not. I'm impressed that Richardson has made her creation feel so truthy - there wasn't anything that jumped out and made me think that couldn't be an Egyptian legend.
Hopefully the library has book 6! :)
