I'm torn between a 3 and a 4. The ending frustrated me just a bit, but I have a feeling that my dissatisfaction was less about what the author did and more about the options I feel like she didn't even consider.

She totally could have pulled an "Aerin and Tor" from Robin McKinely's The Hero and the Crown and she didn't and I'm annoyed.

This book is a gorgeous blend of Malaysian culture and mythos with one of my favorite genres ever - the gothic novel. It's got arranged marriages, ghosts, conniving female "friends", dead parents, obnoxious yet attractive men and, oh yes, a house. If this genre is not your jam, as they say, then I can totally understand finding the young ingenue frustrating and the plot slightly ridiculous. But for me, it's such a grand meeting of literary conventions that I can't help but appreciate it.
Although, apparently, I found the ending rather more frustrating than I'd anticipated.
