I started reading this series in 2012 and finished Book 1 through 3 and the others (Book 4 through 6) have been on my to-be-read list forever. I was glad to get back to this series as I have missed these characters. Dana Cameron is a great story-teller and does not disappoint. The plots are believable and keep the pages turning until the end. I now look forward to reading the last 2 books and I highly recommend this series to those who love great mysteries that involve archaeology.
