The Defiant Heir (Swords and Fire #2) by Melissa Caruso
Cover & synopsis from goodreads:
Across the border, the Witch Lords of Vaskandar are preparing for war. But before an invasion can begin, they must call a rare gathering of all seventeen lords to decide a course of action. Lady Amalia Cornaro knows that this Conclave might be her only chance to stifle the growing flames of war, and she is ready to make any sacrifice if it means saving Raverra from destruction.
Amalia and Zaira must go behind enemy lines, using every ounce of wit and cunning they have, to sway Vaskandar from war. Or else it will all come down to swords and fire.
A return to the world of Swords and Fire, this time with Amalia becoming deeper entrenched in the politics of the Serene Empire while also seeking ways to improve the lives of mages. While stepping up into her role as the heir to the Cornatto family, she finds herself juggling her desires and what she considers to be the greater good. Amalia has to consider what she is willing to sacrifice and whether the cost is too high.
I was surprised to learn that this was a series as the first book wrapped up nicely enough that it felt like a standalone, but I did love the world and characters so I was thrilled to learn that their journeys continued. It was great to see how the characters continued to develop, with book-loving Amalia taking further steps into the realm of politics and gaining alliances such as considering political marriage with a witchlord. I really enjoyed the new characters that were introduced and how they shook up the dynamics among the existing cast. Zaira remains championing for her freedom and the freedom of the other mages, and successfully convinces Amalia to use her position as the Cornatto heir to begin enacting change. The expansion of the political world was also fascinating, to see how other nations were run along with the continuation of the Vaskandar plot threads from the first book.
