I really like Elly Griffiths and I guess I now have to go back to start the series from the beginning. Good writing, appealing characters, twisted plots that I don’t figure out until the end and lots of archeology and pagan traditions thrown in. I did notice that her “families” are largely non-traditional — I actually had a little trouble keeping up with who was partnered with whom and who fathered whose children — but found the variety interesting and possibly more in keeping with the times? Gorgeous (but not too lengthy) landscape descriptions of Norfolk and coastal environs. This is #11 and I’ve only previously read #9. The characters definitely develop across the series so while I was never “lost” I definitely need to start at the beginning if I want to get to know the people as well as enjoying the story. Unlike some other series I’ve read, she is still pumping out full stories and not bulking out with lots of filler because the basic idea has run out of steam…
Books to look forward to ... 
I reviewed her stand alone book and loved her writing so much that I had to read this series. I’m nearly finished with it now and just discovered that there is another one!! More reading – more fun. Great post!
Sounds like a series to try.
