I came to "The Demon Prince" last, after reading all of the other Vampiris Sancti books (well, all the ones that have been written so far), and I think this was a good one to save for last. By this time, I'd already encountered Zyre, the mischievous elf, several times, as well as the demon prince Vyrn Dhaigre. I also was slowly getting familiar with the world the author has created, with its population of demons, elves, gargoyles, pixies, vampires, and other magical creatures.
In this installment, the focus is on Vyrn Dhaigre, who has been obsessed with Zyre for years--demons often become obsessed with elves, and he is determined to have her for his own. He succeeds in setting up an arranged marriage, though his problem is keeping Zyre in one place long enough to have any real interaction with her. Though at first she's reluctant (and I remember her reluctance to lose her freedom from one of the other books), eventually through a give-and-take relationship of flirtation and sacrifice, they come closer together.
They do this while both dealing with the jealousy of Taryst, once betrothed to Dhaigre and now determined to make him pay, and the schemes she sets into motion. While the plot is complex and weaves in a large number of characters, its heart and its most enjoyable moments are those between the elf and demon prince. She's whimsical and charming, capturing first his obsession and then his heart with her own goodness, and he's brooding and charismatic, drawing her to him against her will.
I would recommend this novel to readers who enjoy fantasy novels, especially novels with an intricately created fantasy world and with a romance that grows and blossoms, rewarding the reader with its depth.
