The story

This September, the water
started keeping score.

Every Labor Day the Pophams descend on the family compound — to drink too much, dock the boat badly, and ignore the grandmother at the bottom of the lawn.

By the time the causeway floods and the island cuts itself off, the family has bigger problems than who forgot to call Gram on her birthday. The great white cruising the Sound has been trained, all season, to come when the dinner bell rings. And someone on this point has been ringing it.

One road runs onto Mooncusset, and it floods at high tide. After that, the family leaves the way the tide decides — one at a time.

JAWS with a body count of in-laws — Friday the 13th meets Succession with a Bad Monkey voice. A Cape Cod horror story about a family that finally gets the summer it deserves.

First pages

Tanner Vinick had not brushed his teeth in nine days, and he wanted the internet to know why.

He propped the GoPro on a knuckle of driftwood, angled up at a sunrise that had not shown up yet. The water sat flat and black and very quiet. Out past the sandbar nothing moved — which on the Cape in September is not the same as nothing being there.

The island

Mooncusset.

One causeway in. It floods at high tide. After that, the only way off the island is the way the family is leaving — one at a time.

The great whites really came back to Cape Cod — the Atlantic White Shark Conservancy tracks them live. The book is the only part we made up.

The notes

Every body gets a note.

Each one is left a card — handwritten, passive-aggressive, fatal. Nobody will say who's been writing them.

Found on the first body
“You never called.”
Tucked in a life vest
“You missed my birthday.”
Pinned to the dock
“You sent a card instead of coming.”
Left in the boathouse
“You used the house. Never me.”
What the Water Remembers
Brush your teeth, for the tide tastes a coward. Never say you will be right back. Keep to the many; the one is the meal. When the dog will not follow, do not. Call home your blood, while the line still answers.

The deck is real
CHUM: Blood in the Water

An 18-time Ironman and deep-tech entrepreneur, he knows exactly how a body behaves in a riptide — and has chosen to use that knowledge irresponsibly. Blood Relatives is the first book in the CHUM universe, where the sharks are real and the relatives are worse.
