Full review posted HERE on The Book Addict's Guide 10/1/14: ** This is an honestly, truly SPOILER-FREE review of Mortal Heart! Only details are how I felt about things and never exactly WHAT they were. Too many incredibly special moments and reveals to spill the beans in a review! Enjoy! ** 
 Not that I didn't love the other two books (because I did) but I have been waiting for Annith's story since we first met her in GRAVE MERCY. You guys... MORTAL HEART does not disappoint. In fact, for as much love as I had for the first two books, my love for MORTAL HEART soared above and beyond my expectations. It has the answers to everything and I mean EVERYTHING. 
 Oh my gosh, how do I even write this review without telling you all of the amazing plot points that I surely don't want to spoil? Okay. No spoilers... I will just touch on things we learn! 
 We get to know more about Annith's past. I have been dying to know more ever since we first met Annith so this was SO exciting. Not only do we get to learn more about her as a person, but having Annith's story be the last in the series really ties everything together! 
 YES, there IS a romance and it is super swoony. I mean, did you have any doubt? Mysterious, brave, broody... And he and Annith have great chemistry. The more I read about these two, the more I fell in love with their romance. It was truly awesome, incredibly deep, and also incredibly interesting. 
 There are mysteries galore! And even more importantly, we get all the answers!!! We've been wondering all along why Annith has been kept in the convent. There are hints at different characters being involved in different plots. There are plots of murder. There are family histories. And the reveals for each question that pops up is perfectly timed and utterly amazing. 
 It is really and truly hard to discuss MORTAL HEART without any spoilers because it's the finale of this epic series and I immediately just wanted to discuss ALL THE THINGS. Robin LaFevers totally nailed it with MORTAL HEART and this is the book in the series that I really connected the most with. Annith was incredibly relatable, entirely badass, and fiercely determined. One thing that I loved was how Robin LaFevers really managed to create three entirely different heroines between Ismae, Sybella, and Annith but still keep many of the same basic qualities and ultimate goals. These girls had so much in common and the their stories all intertwine perfectly to create this series, but each one definitely felt like a very different person and a very strong personality. 
 The relationships in this book are just amazing. Of course the romance because WOW, but every relationship -- the good and the bad -- was just so perfectly shaped. The way Annith interacts with everyone -- her feelings, her reactions, her decisions to trust -- just felt so genuine and I really connected with her as a character. She had a lot to gain and a lot to lose all at once and so much of that was based on her relationship with her friends and Daughters of Mortain, with the convent, and with her possible enemies. 
 The plotting throughout the whole His Fair Assassin series is amazing. I enjoyed the first two books immensely, but with everything coming to a conclusion in MORTAL HEART, the action, the mystery, and the adventure really took off in this book and I could not put it down. If you loved the first two books, I don't see how you can possibly be disappointed by MORTAL HEART at all. This book just floored me in all the best ways and I wish I could just soak in it forever.
