Experience the journey of a love story that stretches from the far reaches of the universe to the Appalachian trails of the northeast. Pine Grove has always been a peaceful place, and sixteen-year-old Marley feels right at home in the Appalachians. Things change when a close encounter of the third kind leaves a glowing mark on her shoulder, and a new boy shows up at school. A peculiar glimmer in his eyes reminds her of fireflies, both captivating and scaring her right out of her boots. When he reveals that he’s a host for alien symbiotes, it sends her running in the opposite direction...that is, until he catches her.
