Sam Hawthorne thought he was done with Harbor City's glitches.
He was wrong.
Ever since the fort, something has been following him. Not a shadow. Not a figure. Just a sound - low, rhythmic, rolling up through the concrete floor at night like the earth has a throat.
Sam does what Sam always does. He builds a sensor. Logs the data. Looks for a boring explanation.
His Arduino has other ideas.
LISTENING? LOW TIDE DETECTED NOT WHALE
He didn't write those lines.
And when the tide goes out further than it's ever gone before, something in the cove stirs. Something old. Something that's been waiting for the right frequency to find it.
Something that's already heard the sound coming from inside Sam's chest.
The harbor has a lullaby.
You don't choose to learn it.
It chooses you.
