I love the Mercy Thompson books, and this one is a continuation/spin-off of that world. It is about Samuel's brother, Charles, and his newly found mate, Anna.
Since Charles lives in Aspen Creek, Montana, we get to learn a lot more about the Marrok, his home and his pack. I really enjoyed this, and look forward to reading more in the future.
However, I was seriously confused when I was reading the book. There are frequent, detailed, references to earlier events, and yet this is the first in the "Alpha and Omega" series. I even re-read the Mercy Thompson books (hardly a chore!) to see if I had missed the plot development there.
But my confusion may be solved. I think that Anna and Charles met and "clicked" in Patricia Brigg's short story, which can be bought in the "
On the Prowl" collection of stories. I can only assume this from one of the detailed reviews written for Patricia Brigg's short story in that collection (thank you "clairefromwales"!). I have ordered a copy to check this, and will update this review once I have.
So my suggestion - I think you should read that short story before this book. Having said that, even without having read the story of their meeting, I really enjoyed it and would definitely recommend it to all those who love the Mercy Thompson world (or, alternatively, it you have not read that series either, then check out at least the first Mercy Thompson book (
Moon Called (Mercy Thompson)) before this one !)
