 The first Elder Races book, Dragon Bound, completely and utterly captivated me. And, as much as I have enjoyed each successive installment in this series, neither Storm's Heart nor Serpent's Kiss appealed to me the way that Dragos and Pia's story did. Oracle's Moon, I'm happy to say, ranks almost as high as Dragon Bound in my estimation. I could never say that Thea Harrison was back--because that would imply that her talent went elsewhere--and it has never done so. But, Oracle's Moon definitely has that extra something special that made me go absolutely mad for her writing in the first place. 
 My love for Dragos knows no bounds, but Khalil is pretty awesome, too. He's arrogant, sexy, powerful and totally alpha. Just the way I like my paranormal heroes. And also like heroes of this type, he has some humbling to do. Because in his heroine, he's met his match. Grace-Oracle, grieving sister, mother-replacement, struggling single parent and recovering accident victim--is plenty ready to take this djinn down a notch or two. Whatever Khalil thinks of Grace in the beginning (and it's not in the least complimentary), she doesn't dawdle in setting him straight. 
 Another brilliant aspect of the Elder Races books is that each successive volume does more than introduce a new cast of characters and a new romantic pairing. It also unveils a new layer of the Elder Races world. I learn some new trick, rule or aspect each time, often about a new demesne. How Thea Harrison manages to keep all of these details in her head at one time, I'll never know. It's awe-inspiring, and she deserves props for that alone. 
 While world-building is certainly one of Thea Harrison's strengths, I think I love her characters most of all. Grace is fantastic. She's down-on-her-luck, but still kicking. True, a part of this is due to the fact that she has two small children to look after. She doesn't have the luxury of giving up, no matter how hopeless things get. But she's a take-charge kind of woman, anyway, and she's clear about her boundaries. With Khalil, and with others. You gotta admire that. 
 Khalil, too, is a fascinating, irritating character. He may have great supernatural powers, but he's not omniscient, and to watch such a powerful being make mistakes? One can't help but be amused. He's also the only person (or being) that I buy being able to stand up to Dragos and get away with it. But best of all? The kids. I loved them. I adored little Max and spirited Chloe. I could picture them perfectly in my mind, down to the way Grace felt when she held them in her arms. Kids are awesome, and frustrating and wonderful. Harrison captured that beautifully. 
 Oracle's Moon has been out for a while now, so I surely hope you've already purchased your copy. If you haven't, I tell you, you're seriously missing out. It's a fantastic addition to the series. But don't take my word for it. This is one you have to experience for yourself. 
 5 1/2 Points: 
 I would have this book's babies.
