For five years, Lyra Bennett and ZeroTrace have been best friends online. They game together every night, share their secrets, and know each other better than anyone else—without ever learning each other’s real names. Lyra likes it that way. Adrian Hale doesn’t. The moment he discovers Moonlight’s identity, curiosity turns into obsession. He starts watching from afar, learning everything he can about the woman who’s become the center of his world. Lyra has no idea her closest friend is the reason every date goes wrong, every potential boyfriend disappears, and every path somehow leads back to him. Because Adrian isn’t willing to share. And the closer Lyra gets to uncovering the truth, the more dangerous his obsession becomes.
