This was a fun read. Bear with me while I free-associate: this had a slightly over-the-top, mystery plus supernatural vibe, kind of like watching Remington Steele, or like being twelve and thinking you'll marry a detective and travel the world solving crimes. And also you'll have a magic necklace! Because that is totally a thing that happens when you get married: your husband gives you a magic necklace and you can hear the ghost-- sorry, the ba--of an Egyptian mummy.
So it's a little bit of a "turn your brain off and just enjoy" book, but it's very well-written, and I am hooked. And LUCKILY I bought both this book and "The Mummy Beads" at the same time, because while the heroine and hero are sort of "together" by the end, the book actually ends with THE HERO'S PLANE CRASHING. He sneaks away in the middle of the night, and the heroine wakes up not knowing where he is, and a cop comes to the door to tell her HE'S DEAD. Obviously he isn't dead, since there's a whole second book where she goes in search of him, but it was still a bit startling in a category romance. I don't think I've ever read a Harlequin with such an ambiguous-for-now ending.
