I ended up reading this because Lynn mentioned it, and I felt like something fairly light and quick. This worked for that, and as a bonus, the worldbuilding is great. It’s not just the sort of story where the plot and world are a sketchy scaffold for a romance to hang on, but a world that feels much bigger, that invites more story and asks you to imagine the past and future of the world it contains.
It helps that the two main characters are fun — funny, in Shan’s case, and adorably awkward in Tirellian’s — and their relationship feels real. The way things work out between them feels right and natural, fits perfectly in the story and in the world, without taking away from everything else that’s interesting about the story. There’s no sudden three chapter interlude of sex before the plot gets underway — while there are some sex scenes, and you don’t have to read them to follow the plot, the point of the story is not about the sex; the sex is just part of that relationship, which is just part of the world, etc.
All in all, definitely a fun one, and I need to hurry up and read The Lodestar of Ys, clearly.
