I've been reading Mercedes Lackey's Valdemar books for about seven years or so; I was keeping my ex-wife company while she worked on her fish tanks, and picked up Magic's Pawn
It sounds dire, I know, but they're entertainingly written, with Lackey taking a different tack on that basic theme in her several series set in and around the Kingdom of Valdemar. She does action well and, if the romance is a little bit predictable, it's seldom cloying and usually somewhat realistic (especially as she's somewhat leaned off the mystical Lifebond as a trope), with disagreements and miscommunications and actual communication solving more problems than it causes.
But, Closer to Home
In reading book, however, it slowly dawned on me that she was somewhat retelling Romeo and Juliet; two warring families, in the capitol city for the Winter Court (hoping to find spouses for daughters and a son, respectively), who simply cannot be in town without trouble starting. Mags, Amily, and the other Heralds do their best to keep things from going to pot, but humans are determined to be difficult, and a plot develops that could burst this feud into an all-out civil war. Things are a bit telegraphed, but I was thrown when she decided not to go the full Romeo and Juliet and more closely adhered to William Goldman's 'What happens when the most beautiful girl in the world marries the handsomest prince in the world - and he turns out to be a son of a bitch?'
I enjoy the heck out of Mercedes Lackey books. They're fun, enjoyable reads that are nonetheless well put together and tend to somewhat meditate on the nature of power and its exercise. She's set herself a lovely world that she works with, finding new variations on similar themes, and expanding her own world, rather than breaking it, to introduce new things. If you'd like to start at the beginning of Mags' story, instead of here, start with Foundation
