The Skinny: 
 A book that can be summarized in ten pages. AKA just skip to the last few chapters to get the gist of the book. 
 The Fat: 
 In first half of the book, Celaena is still trying to recover emotionally from Choal's betrayal and Nehemia's death in Crown of Midnight. She is depressed and is struggling to not stay emotionally numb. She wastes her days stealing food and wine, and she spends the nights fighting in street brawls. Until one day Rowan takes her to see Maeve. 
 Heir of Fire (HOF) takes place primarily in three locations: Adarlan (mostly Rifthold), The Ferian Gap, and Wendlyn. I wish that Maas had included a map of Wendlyn, because I find maps incredibly beneficial when reading fantasy novels. So I was a bit disappointed when there was no map to reference half of the storyline. 
 I was very happy that readers still got to read Choal and Dorian's stories. I was afraid that since Celaena went to Wendlyn then I would have to go a whole book without them. But fear not! Both characters are included. 
 Maas has added many different characters and POVs. Readers finally get to read about the infamous Rowan and Manon. I loved both characters. They both are violent (and at times heartless) characters, but they each have incredible depth. Manon is my favorite new character. Her storyline primarily deals with training wyverns and every scene kept reminding me of How to Train Your Dragon. It was marvelous. 
 Some other new characters are Sorscha and Aedion. It felt like Sorscha was added simply so Dorian had a love interest and that kind of pissed me off. She really wasn't a necessary character (until the last ten pages). Her relationship was cliche, predictable, and felt forced. Aedion was a fascinating character to read. I won't say more than that because I don't want to spoil anything, but he has incredible depth. 
 It was incredibly hard for me to put down HOF. Even with my insane workload from school, I still found myself trying to make time to finish it quickly. However, when I had about 100 pages left, I realized that not a lot actually happened in HOF. Most of it could have been summarized in just a few pages. Even though the book was addictive (and this could be due to the fact that I wanted to avoid doing any and all schoolwork), the fact that all the important parts happen in the last 50 pages is frustrating. It doesn't help that the book spans months and so little actually occurred. 
 I think why I was so eager to keep reading was because as soon as I got invested in a character's storyline, then the POV would change and I would have to keep reading to return to it. I wish that POV changes were more consistent. Sometimes one character would have multiple chapters back to back of POV and other times five chapters in a row would be POV changes. 
 Readers learn a lot more about magic, faeries, Wyrdkeys, and Celaena's past. The ending was very intense. The last 20 or so pages were a HUGE surprise. That was the only plot twist I didn't see coming. Unfortunately, the others were predictable. 
 Favorite quote: "She was the heir of ash and fire, and she would bow to no one." (page 499) 
 When I first started reading HOF I was convinced that it would be a five star rating, but as the book went on I felt less inclined to give it five stars. Nehemia's death seems even more pointless now than it did in COM. Honestly, she just died for shock value and the series would have been much better if Nehemia had lived. The romantic relationships felt forced in HOF. The book, although a good read, was mostly just a filler for the next in the TOG series. I hope that in the next book there will be more action.
