Fireflies (Fireflies #1)

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.Meanwhile...Will is entering yet another school midyear. He has his usual problems: acclimate to a new school, deal with his assigned FBI agent, track a compatible human, all while appearing the normal teenage boy. He can't believe his luck when his search leads him to Marley, a girl more agile in the woods than in a mall. He reminds himself that he can't let what happened to his last assignment happen in Pine Grove, not to her...
