Casey's life in Langston has been charmed. She's the queen bee of her prep school, a shoo-in for prom queen, and on her way to the Ivy League come fall. She can't wait to leave the whole town of Langston behind her. That is until her father loses his job and she finds herself on the brink of losing her ticket out of town. The town of Langston is known for its picturesque lake and robust summer tourism. Everyone who lives in town has heard the rumors at some point-- there is a treasure buried deep below the surface that no one has ever been able to find. Few people actually believe in the treasure, and even fewer have searched for it. But some have tried. Suddenly an outcast from her popular squad, Casey falls in with a new group of friends who are exactly the opposite of her usual crowd, but are more accepting. Together they devise a plan to find the elusive treasure, in a quest to get the money and save Casey's family and her future. But what they find is much more complicated than just a pile of gold.
