I don't want to give away too much, but the underlying idea of oaths being bound by magic so that an oath breaker is magically punished has a lot of potential. And the story starts with two boyhood friends who swear an oath of loyalty to each other . . . well, you can see where this is going.*
Raim is a pretty swoon-worthy main character, and I liked the potential love interest (no spoilers here!). I loved the hidden city of Lazar.
There were some first-novel awkward bits, and the magic system hasn't been explained well enough yet, but I'm engaged enough by the story to want to read the second book.
I went looking in my library for Rachel Neumeier because I'd heard a lot about House of Shadows. When I found The Floating Islands, the title and cover convinced me I'd love this book even if I hadn't been interested in the author. I was right.
Loss, betrayal, longing, choices, mistakes, consequences. Noble sacrifices, humility, generosity. These are a few of my favourite things in books, and The Floating Islands has them all. Dramatic scenes where characters challenge each other and reveal their true essence. Characters who desperately want something, and find out they can have it, and then learn the cost. People who can fly. Then there's the titular floating islands. Awesome setting! (What is it about that concept that's so compelling? It makes no sense, but do you remember the ones in Avatar? Amazing.) Loved the islands, loved the relationship between cousins Trei and Araene, loved Araene's taste/scent-based magic, loved Trei's friend Ceirfei (swoon!). (Wasn't a huge fan of all the unpronounceable names!) I would have read a lot more description and explanation, but I liked the fast pace—it was efficient; it gave me everything I needed. I'm definitely reading more of Neumeier!
*Coincidentally enough, I just read Wolfskin by Juliet Marillier, which centers around a similar plot point. Wonderful adult fantasy; my first by Marilllier, though I've been intending to try her for a while. It's in my TBReviewed pile now.
