Depth. A Carter Family Shark Thriller, #3

A research vessel. A haunted ocean. Sharks that don't let go. When marine biologist Ryan joins the aging research vessel Queen Velvet, she's not looking for adventure, she's running from a past that still smells like blood. Years ago, her father died at sea, torn apart by something massive beneath the waves. Now she's back on the water. As the ship pushes farther offshore, two enormous sharks begin stalking the vessel, circling with unnerving precision.
This isn't a random encounter. These predators follow, wait, and strike with intent, as if they remember her. Trapped at sea with a failing ship, a fractured crew, and predators that refuse to disappear, Ryan must confront the truth. Some sharks don't hunt for food. They hunt for revenge. The crew of the Queen Velvet never sees it coming and by the time they understand what's following them, escape is impossible.
They hunt. They follow. They remember.
