Three more voices came through the radio.

Ivy.

Willow.

Hazel.

All five Sinclair sisters were connected.

Not in one place.

But together.

Exactly as James had intended.

Hazel’s voice came through first.

“There’s a switch beneath Grandpa’s chart table.”

“Don’t touch it yet,” Storm said.

“I wasn’t going to.”

“You already touched it, didn’t you?”

A pause followed.

“Maybe.”

Ivy spoke in the background.

“It turned on an old transmitter.”

Willow interrupted.

“And something is clicking behind the engine-room wall.”

Storm looked at Thomas.

“What did Grandpa build into Sea Whisper?”

“More than a yacht.”

“That isn’t an answer.”

“It’s the only one I have.”

Storm’s expression hardened.

“Thomas.”

He finally sighed.

“James began building Sea Whisper after Daniel died. Every wire, every radio, every navigation system passed through his hands.”

“He used her as part of Blackwater’s controls?”

“He used her to make certain the gate could be closed even if you girls were scattered across the ocean.”
