I read Grave Mercy not long ago, and thoroughly enjoyed it. Dark Triumph is the second book in the trilogy, and picks up right where Grave Mercy lets off. Instead of following Ismae, though, we follow Sybella. The two could not be more different, and I loved seeing the world through Sybella's eyes.
Even though we weren't with Sybella in her life before the convent, we can guess just how horrific it was based on the kind of people she grew up with. I thought LaFevers did an excellent job of slowly revealing her history to us, and by the end I felt I knew her well and could understand why she came to the convent half-mad.
The romance was well done, slowly building in a believable way. I loved watching the relationship build between Sybella and Beast, but the transition from friendship to love happened a little too suddenly. I can see the signs that they like each other, and are even attracted to each other, but the leap to 'love' was a bit too quick. Still, I like them as a couple, and think they are good for each other.
I also enjoyed seeing the abbess through Sybella's perspective. She's so different with her than she is with Ismae, and it's clear her reasons are personal. I have a pretty good guess as to why, but I won't spoil that for you. :)
My favorite part of the story is watching Sybella come to terms with Mortain, the god of Death. Unlike Ismae, she has doubts as to his existence. With the childhood she had, I think this is quite normal. She comes into her faith in a roundabout way, which I found realistic and believable.
I'm really looking forward to the last book in the trilogy, which will follow Annith. The only bad thing is I have to wait until next year...
