Christy's off traveling in the Middle East, where she springs a surprise visit on an eccentric great-aunt and runs into her cousin. She hasn't seen the great-aunt since she was a child, and the aunt - living like Lady Muck out in an old and half-ruined palace - is distinctly weirder, and more suspicious, than Christy remembers. Turns out there's something dodgy going on in the ruins, and if you go into this hoping, as I did, for some sort of Hound of the Baskervilles vibe (to be fair the blurb did give me that impression) you'll be disappointed. There's nothing ghostly or supernatural going on here. 

The most disturbing thing is, frankly, the romance. It's between first cousins, so from the get-go it verges on incestuous, but so much is made of the fact that these two are routinely mistaken for twins that is goes straight past verging and into actual. I can't help but picture them, post-novel, married and being taken for siblings, which is not that appealing, frankly. I think it's also fair to say that the book is fairly slow-moving, and while the action does pick up near the end, a lot of it is Christy traveling to various places and having near misses with people she should be meeting, which is not all that exciting. It's a bit flabby in the middle, is what I'm saying, but it's still mildly entertaining.
