The quest for the final star leads the group of six guardians back to Ireland, where deep roots lie for Bran and Doyle. 
 This book explores the connections of the characters and their ancestors leading back to the goddesses. I enjoyed the search for the star as I did the first two books. The only thing I wanted more was the connection between Riley and Doyle. It felt more like a relationship of convenience. They were the only two single people left, and even the beginning of their relationship was a no frills enjoy it while you can sex. I wanted a little more than that for them. 
 Overall, I still enjoyed the story and the epilogue was nice. Would've liked to see them a few years down the road to see how they lead their lives though.
