Lilith Bennette runs at midnight. She scales walls in the dark and climbs without a harness. She hopes if she follows exactly in the steps of her strong air force pilot mother, she'll somehow figure out the mystery of her mother's death - and the reason why her necklace of Greek symbols has been missing ever since. When Lil is invited to Crete for a Future Leaders International conference, the same conference her mom attended years ago, she jumps at the chance to find some answers. What secrets does the labyrinth hold, and will they help Lil find the truth about her mother? This book is perfect for older fans of Percy Jackson and the Olympians and the Heroes of Olympus.
