Leonie Simoneaud was once one of the elusive Lake People - Acadian descendants in Louisiana with odd psychic powers. As a 13-year-old, she rescued an outsider child, Douglas Trent, from a maniacal pedophile named Monroe Whitechapel. Consequently, she was shunned by most of the Lake People for exposing them to the external world. As an adult, she lives elsewhere, an owner of an antique store in a quaint Texas town: Buffalo Creek. However, she doesn't know that she has been targeted by another madman for a reason that has everything to do with her rescue of Douglas. Her friends are under attack, and her psychic powers have been revealed to the people of Buffalo Creek. A child has been kidnapped, and a backpack with a riddle inside was left on Leonie's porch. However, only Douglas and Leonie know that Monroe Whitechapel used riddles to taunt his many victims - and Leonie killed Whitechapel when she saved Douglas. It will take every drop of determination inside Leonie to unravel the mystery, and she will learn a desperate truth about a psychotic man she killed 20 years before.
