I'm a bit sad to reach the end of the His Fair Assassin series...perhaps there can be a follow up series that continues to detail the life of the Duchess? Mortal Heart starts up during Dark Triumph (I think) but from Annith's perspective. She's been referenced multiple times in the first two books as being stuck back at the convent and not being sent out on a mission despite being a super fabulous student. While Annith's ultimate calling is quite apparent from the beginning, her story takes some unexpected twists along the way. This book dwells much more in fantasy than the other two. I found it hard to imagine exactly how some of the new unearthly characters should appear/how they would appear to our human protagonists. Overall, I enjoy hanging out in 15th century Brittany with some tough, weapon-wielding ladies. (view spoiler)[ But again, why must they all end up with a sigh happily ever after dude? Come on, YA fiction, not all young ladies need a man to have a happy ending...no double entendre intended there. (hide spoiler)]
