The Whisperwood Legacy — Jo Schulte

Knives Out meets The Hazel Wood in this twisty contemporary fantasy about an amusement park shrouded in dark secrets -- and the family desperate to inherit it at any cost. 
 
Welcome to Whisperwood, a sprawling theme park nestled in the foothills of the Appalachian Mountains, where thrilling rides and picture-perfect scenery bring cult-classic fairy tales to life. Or at least they did until eighteen months ago, when the family matriarch, Virginia Strauss, suddenly shut Whisperwood's gates and the beloved park was left to wither away along with the family's dwindling fortune.
  
For seventeen-year-old Frankie Strauss, Whisperwood's closure has been a blessing in disguise. After seeing three generations of wealth's corrupting influence, she is more than ready to shed the Strauss-family's gilded handcuffs.
  
But when Virginia goes missing, Frankie realizes that her family might be guilty of something much worse than mere dysfunction. With the help of the mysterious and handsome groundskeeper, Jem, Frankie sifts through a web of near truths and outright lies, uncovering a reality where nothing is as it seems and fairy tales aren't just real -- they're deadly.
