Queen of Hearts

"Alexandra Dubois, a NYT bestselling author, has made a name for herself by crafting twisted serial killers in her romantic suspense series. When threatening notes from an "invested reader" escalate into violence, Alex has to admit she's not safe in her own home. Although her autism makes any changes to her routine difficult, she reluctantly accepts her editor's advice to fly to his sprawling vacation home in West Virginia so she can focus on her looming deadline." -- www.goodreads.com
