It's good to know that you liked the first 2 Peter Mays Hebrides books, I expect I'll like them, too. I'm wondering how long it will take for #3 to come in.
Sundstøl's second book struck me as something of a placeholder, not as much fun to read as the first one. But I wouldn't have wanted to not read it, some questions are answered - not all of them, of course.
The Rickman series sounds interesting, I do find all things Welsh quite intriguing. Thanks for sharing your story. While it's far outside of the type of books I generally choose, I'll keep this series in mind should I find myself wanting something completely different from my usual reading fare.
I read The Secret Place several months ago - I adore Tana French! I found it utterly fascinating - so much so that once I finished the last page, I immediately turned back to the beginning and read it all the way through again.
Now I'm all caught up on all of Tana French's novels (hope it's not too long before there's another). So far, Faithful Place remains my favorite, with The Secret Place a close second. After I finished The Secret Place (twice!) I ordered all her preceding books from the library and read all of them through again in order. I had a lovely week of gorging myself on all Tana French all the time!
She and Arnaldur Indriðason are definitely my favorite authors.
