FBI profiler Harper Sloan is used to chasing darkness - long hours, brutal cases, and the constant weight of knowing the minds of monsters better than her own. But when a series of violent crimes unexpectedly end up Seattle at the same time she's visiting her brother, Harper finds herself forced to walk the line between the horrors she hunts and the family she's nearly lost to time. Her older brother, Mark Sloan - renowned plastic surgeon, legendary flirt, and fiercely protective big brother - isn't thrilled to see his sister tangled in another high-risk investigation. Especially not when it's happening right in the city he calls home. Alongside former childhood friend and neurosurgeon Derek Shepherd, Mark is determined to give Harper something she's never had: space to rest, people to lean on, and a reason to stay. As Harper balances high-stakes BAU cases with the chaotic rhythm of life inside Seattle Grace Mercy West, she begins to rediscover what it means to be more than a profiler - to be a sister, a friend, and maybe even something more. But the closer her work gets to Seattle's heart, the more the lines blur between healing wounds and confronting old ones. Because monsters don't just live in the field - sometimes, they hide in the places we thought were safe. {Spencer Reid x Lexie Grey} {Aaron Hotchner x Original Character}
