Apparently this is a sequel to The Summer Country (by the same author), but oh well.
To be absolutely honest, the only reason I picked up this book was because, as the blurb on the back tells us, there's a dragon called Khe'sha. I giggled a little bit (I mean, who wouldn't?), and decided that what the heck, this 295-page-long fantasy novel (magic! People with the Old Blood can wield Power! And Important Words are always Capitalized!), with a partial setting in the real world and a partial setting in a Celtic fantasy world, and several nods to Arthurian legend.
It was okay - at times I felt like I missed something that would explain some of the characters' motives (as in, why does Jo suddenly decide to, um, try to convince policepeople that she had killed her father? What? I don't get it!), and I got a few "um, what? Why?" moments, but it's all right. I was still reasonably entertained.
