Winnie Wednesday has gotten everything she thought she wanted. She passed the deadly hunter trials, her family has been welcomed back into the Luminaries, and overnight, she has become a local celebrity.

But none of it feels right.

For one, nobody will believe her about the new nightmare called the Whisperer that's killing hunters each night. Everyone blames the werewolf, even though Winnie is certain the wolf is innocent.

On top of that, following her dad's convoluted clues about the Dianas, their magic, and what happened in Hemlock Falls four years ago is leaving her with more questions than answers.

And, unfortunately, there is still only one person who can help her: Jay Friday, the boy with plenty of problems all his own.

As bodies and secrets pile up around town, Winnie finds herself questioning what it means to be a true Wednesday and a true Luminary—and above all, where her fierce-hearted loyalties might ultimately have to lie.
