Heir of Fire by Sarah J. Maas is the third book in the Throne of Glass series. At the end of the last book, Celeana Sardothien discovered that she was really Princess Aelin Galathynius, heir to the throne of Terrasen. Now she has traveled to Wendlyn to meet Maeve, Queen of the Fae to find out what the queen knows about the Wrydkeys, a weapon being used by the evil king of Ardolan. But before Celeana can get the answers she seeks, she is forced into a training program to develop her fae abilities.
Back home, Celeana’s cousin Aedian, whom she hasn’t seen in years, has traveled to Ardolan and met Chaol of the King’s Guard and Prince Dorian. Both Chaol and Dorian seem to have matured since the last book. Chaol is trying to make sense of Aedion’s resemblance to Celeana and where his true loyalties lie. Dorian is trying to forget Celeana and is back to his womanizing ways. Or is he really?
Maas also introduces a coven of witches in this book, who are in serious training for something. An upcoming war, perhaps? And who are they working for?
Heir of Fire is a good continuation of the Throne of Glass series, furthering the story of Celeana, once a notorious assassin and now a royal heir. Read to find out how she accepts more challenges to determine her true fate.
