Burning Roses by SL Huang

Rosa, also known as Red Riding Hood, is done with wolves and woods. Hou Yi the Archer is tired, and knows she’s past her prime. They would both rather just be retired, but that’s not what the world has ready for them. When deadly sunbirds begin to ravage the countryside, threatening everything they’ve both grown to love, the two must join forces. Now blessed and burdened with the hindsight of middle age, they begin a quest that’s a reckoning of sacrifices made and mistakes mourned, of choices and family and the quest for immortality.
