This is also the beginning of the storylines that seem to focus a lot on a family of royals who really understand the Tradition and how to use it to their benefit. So Sasha, seventh son of the king, plays the fool in public, but in the rare moments of privacy, his family cherish their good fortune in having him--because in Traditional manner, things just naturally go his way.
When he meets Katya, a princess from a very different kingdom, things heat up right away between them (naturally), until they catch the attention of one of those magic-power grubbing Jinn the Tradition is so likely to throw your way in this world.
I thought this story was one of the strongest in the series, mostly because there was enough plot to keep things rolling steadily. Lackey incorporated the folklore of more than European culture, here, as well, which always changes things up a bit. Also, the spicy romance didn't hurt.
