Margot Holloway built a forty-million-dollar wellness brand on moonwater, smoothies, perfect captions, and pretending she has her life under control.

Then a customer finds a wolf hair floating in a bottle of her premium spring water.

Not a metaphorical wolf hair.

An actual wolf hair.

When Margot drives into the Cascades to confront the supplier, she expects apologies, refunds, and a very fast quality-control meeting. She does not expect Eli Marston.

Grumpy. Huge. Flannel-wearing. Painfully calm.

Also, according to him, a werewolf.

Eli owns the spring that supplies Margot’s bestselling moonwater. Unfortunately, the water has been accidentally contaminated with trace lycanthropic plasma. Even more unfortunately, Margot has been drinking it every day for three years.

Now the next full moon is seven days away, her body is doing things no wellness podcast has ever prepared her for, and Eli insists she stay at his remote cabin until the danger passes.

Margot has a launch to manage, an ex-fiancé stirring up headlines, a brand to protect, and absolutely no time to be trapped in the woods with the hottest, most irritatingly responsible man she has ever met.

Eli has rules.

Margot has a phone.

Neither of them has enough emotional distance for one cabin, one fake soft-launch photo, one kitchen hatchet, one forbidden smoothie, and seven days of pretending this is only medical observation.

She came to fix a contamination crisis.

He was supposed to keep her from turning.

But somewhere between the satellite phone, the grilled cheese, the fake dating rumors, and the full moon getting closer, Margot starts to realize the real danger may not be the wolf in her bloodstream.

It may be the grumpy alpha who sees straight through her brand and still wants the woman underneath.
