Just finished my third reread of 'Alliance Broken' last week, and that question really gnaws at you, doesn't it? By the novel's final pages, I wouldn't say the central alliance is 'resolved' in a neat, tied-with-a-bow sense. The treaty itself is technically reinstated, but the foundation is utterly different. It's less a resolution and more a painful, fragile rebuilding on entirely new terms, with all the old trust completely shattered.
The epilogue with Liora and Kael silently sharing watch on the ramparts says everything. They're cooperating because the existential threat is still there, but the easy camaraderie from the first book is gone forever. The resolution is the acknowledgment that some breaks can't be fully mended, only worked around. It feels true to the political mess the author built, even if it's not the cathartic, united-front victory some readers might crave. The book ends on a note of weary, pragmatic peace, not a celebration.
