How do you solve a murder that hasn't happened yet? Destiny Whip is a former child prodigy, world-renowned enigmatologist and very, very alone. A life filled with loss has made her a recluse, an existence she’s content to endure until a letter arrives inviting her to interview for the position of Scruffmore family historian. Not only does an internet search for the name yield almost nothing, it’s a role she never applied to in the first place! She decodes the invitation's hidden message with ease, and its promise to reveal her family secrets proves too powerful a draw for the orphaned Destiny, who soon finds herself on Eerie Island. It’s a place whose inhabitants are almost as inhospitable as the tempestuous weather.

The Scruffmores themselves turn out to be not much better, a snarled mess of secrets and motives connected by their mistrust for one another. Their newly arrived guest proves to be just as much an enigma to them as they are to her. While Destiny slowly works to unravel the mysteries hidden throughout the ominous castle, she struggles to interpret disturbing nightly visions of what is to come.

In the midst of cryptic ciphers, hidden passages, and the family’s magical line of succession, Destiny is certain of two things: one of the Scruffmores is going to die and she’s running out of time to stop it.
