Obsidian Flame is the 5th installment of the Guardians of Ascension and is is the best one yet! It follows the leader of the Guardians, Warrior Thorne, and his breh, the feisty Marguerite. Marguerite has been locked away for 100 years, with nightly visits from Thorne her anchor to life. She is set free, and runs to be free of everything....being the 2nd of the powerful flame triad that will help Endelle and the Warriors in the war against Greaves, and most especially Thorne. While she loves Thorne, she loves her freedom more. Without giving to much away, we get to see her and Thorne's journey and the trials they face as they, well she, fight the Breh. We also get more story of Leto and my heart has broken for him. I can't wait to read more and the next installment cannot come soon enough!
