Leading lovers Grace and Khalil are introduced in book 3 "Serpent's Kiss". Grace is "The Oracle"; a position she thought she'd never have to deal with until her sister is killed, whilst Khalil is a second generation Djinn; one of the most powerful of the Elder Races. He isn't impressed much by Grace's attitude when he meets her, whilst she is tired and grouchy after dealing with her nephew and niece whom now live with her, a house falling apart around her ears and mounting money worries. Yet her duty as The Oracle means that she cannot deny a petitioner, so when Khalil, accompanied by Tiago and Carling, turn up unannounced at her home she also has to deal with magic that is still new to her.
Khalil finds himself inexplicably drawn to Grace as well as her young niece and nephew. He grants her one of the greatest gifts he can offer; his protection, yet he is left infuriated when Grace fails to realise the magnitude of what he offers. Grace in turn has a hectic life and doesn't want the addition of a curious Djinn in her home, especially one that interests her far more than he should. Yet when danger threatens Grace and her family, Khalil is handy to have around. But perhaps ensuring Grace's safety will endanger the powerful Djinn himself.
Again TH has created a whirlwind plot line with plenty of action, drama, treachery, passion and some seriously poignant moments. The budding relationship between Grace and Khalil is wonderful (his concept of dating is literally out of this world) plus their banter is thoroughly entertaining. I also enjoyed the ideas surrounding Djinn society, plus Grace's own battle with her magic. 4½ stars
