Perseus (Percy) and Arya are twin wolves born from Alina Heartsbane and Rex Monroe - the Alpha and Luna of the strongest pack in the West, Red Woods. They are days away from their 18th birthday, days from their first shift, and days from hopefully finding their mates. The twins are nearing the end of their senior year and must navigate pack and school life as the family dynamic changes. What will happen to them when someone is coming for their mates?
