Heir of Fire also introduces the Ironteeth witch Manon and the wyverns. As readers get the answer to what’s happening in the mountains (partially), Manon provides a welcome bit of action. I instantly loved the wyvern Abraxos, but unfortunately nothing comes of their storyline in this book.
Will I keep reading? Of course. But I’m an impatient reader. I hope to find much more plot movement in book four, because, though I loved the world-building in Heir of Fire, it did put my patience to the test.
