This is a fun series and I enjoyed all the books, each of which focuses on a different main character. However, of the three main characters, Annith, the focus of Mortal Heart is the one I find the most annoying. For all her capabilities, she’s really extremely naïve, especially given her history. I continually reminded myself that she was just 17 and a lot of people are gullible at that age. As the book progresses and there are plots and reveals, I would routinely see the issue significantly before the main character even though we’re seeing the same evidence. I also felt a bit of a letdown at the end because I saw a potential way for one of the plot arcs to be resolved in a really fabulous way and instead it was sort of semi-resolved in an okay way.
One thing I really enjoyed about this book was the look it gave into what the other eight gods of the old religion have been up to and how their chosen people are marked and what they do with them.
While the grand political conflict seems to have mostly worked itself out over the course of the three books, what happens next regarding the actual convent of assassin nuns is left so very open-ended that it makes me wonder if there might be a fourth book in the planning stages. I haven’t been able to find any mention of one though.
It was an okay book, but I did like the previous ones in the series a lot more. If there is a fourth book, though, I’ll definitely read it to see what happens.
