Initial thoughts: Someone option the Dark Caravan Cycle for film, please! I want to know what happens next without reading the sequels. The prose was exceedingly trite. Nearly every single page referred to chiaan which apparently meant magic, though seemed to coincide with soul as well. I got tired of Nalia's inner chanting, "I am Ghan Aisouri." The romance was so poorly developed, it distracted from what could have been a stellar plot. Exquisite Captive minus the romance and the tiring prose would've made for a far less boring book.
What I did like were the djinn's centrality to the book while humans went on with their lives on the sidelines. I also liked the sinister undertones that the ghoul brought to various places across the world and the rich imagery of culture. On screen, I think these would make for lovely scenes. The special effects, if done well, would make Exquisite Captive a great viewing experience. Even little things like a djinn bartender mixing cocktails by swirling he liquids in the air instead of using a shaker would add to this other-worldly quality.
Alas, the core of books are words first, then the stories they convey. I don't have it in me to painfully plough through the rest of the series.
