Iron Flame is a fantasy book and the second book in the Empyrean series written by Rebecca Yarros. Reading Iron Flame is like riding a roller coaster, which has both ups and downs. The first part was mostly concentrated on the Basgaith War College, which says,”The first year is when some of them lost their lives. The second year is when the rest of us lost our humanity,” which also has so many plot twists. The second part was about the war “The Sea of Venin against Cadets, Fliers, and Leaderships,” which had an unexpected twist at its climax. This is the best book for fantasy lovers, and it’s worth reading.
