"Crystal Bones" is the first book of C. Aubrey Hall's Faelin Chronicles series. In this fantasy novel, readers meet Diello, Cynthe, their little sister Amalina, and their parents Stephel and Lwyneth.
Diello and Cynthe are fraternal twins and considered Faelin because their mother Lywneth is a Fae and their father Stephel is a human. With this the case, there are some milestones in the twins' lives that follow Fae milestones and others that follow humans'.
One of these milestones is the twins' thirteenth birthday. This is when they are to realize any Fae powers they have, and, in the Fae world, acceptance as adult Fae. But the twins, being Faelin, don't really fit into either world, and the birthday is not a happy one. In fact, it goes horribly wrong.
They are sent on an errand, and when they return they find their parents murdered, their farmstead destroyed, and Amalina kidnapped. Their Fae powers are starting to develop, but Diello's gift - Crystal Bones, or the ability to sense magic nearby - is not the one he hoped for.
So, on their own, they must survive, find Amalina, and find where other trustworthy (key word here!) adult relatives are. Their only help comes from a talking wolf puppy named Vassou and an uneducated outcast goblin boy named Scree.
I have read both this novel and the second in the series, "The Call of Eiran." In both, I particularly liked the Welsh flavor the author has given some of the proper names and the fact that the youngsters call Lwyneth Mamee. The one thing I did not like about the two novels considered together is the rather slow pace of the plot. Even though I unintentionally read "Eiran" first, I definitely feel now like I didn't miss anything by doing so. All in all, though, I'll be keeping my eyes open for more in this series and can recommend it for fantasy readers, particularly those about the same age as the twins of this story.
