Jo Mayweather’s not a typical gal—even amongst her fellow Djinn. She hasn’t had to call anyone ‘Master’ since WWII. Unlike most of her kind, she's got no problem living with humans--which certainly doesn’t help her status with the brethren. And while most of her kind are either out enjoying eternity or slowly going nuts from it, she spends her immortality helping others gain their freedom, too. With everything going on in her life, being different doesn’t seem like such a big deal.
When some creepy Efreet starts killing the Djinn Jo’s supposed to save, her whole bizarre world frays like a cheap sweater. It’s bad enough she has a killer to catch, but fighting against a conspiracy of silence shouldn’t have to be part of the plan. Of course, neither should finding out two of her closest friends could be working for a murderer. Needless to say, the whole situation has her doubting everything she thought she knew about being Djinn. With her supposedly-immortal brethren dying around her, though, she’s not going to let something like a little lack of knowledge stop her—even if ignorance could get her killed. Or worse—enslaved again.
That's the latest incarnation. I've looked at it so much, my eyes are going squonky. If this isn't it, I'm at a serious loss.
