The Last Sounding: : A Deep-Water Survival Thriller

THE SEA HAS BEGUN TO GIVE BACK ITS DEAD. Off a cold coast in Chile, a drowned fisherman speaks to his son through the hull of a boat. Within a week there are voices at every shore on Earth - patient, finished, saying goodbye. The world calls it the Knocking. Acoustician Mara Vance, who walked away from the deep three years ago, calls it what it is: a summons. Because her letter came by hand, in her dead sister's handwriting, with a deadline. Sixteen days. Bring the ship. Bring the ones who held ropes. At the bottom of the deepest trench on the planet, a keeper ten thousand years old has decided to empty its house - one planetary broadcast, every kept voice released at once, if it can learn the one skill it never had a teacher for: letting go. But billionaire Simon Aldous is already on station with a private fleet, a crew of the bereaved, and a device named LAZARUS. He isn't coming to say goodbye. He's coming to take his daughter back. Aboard the RV Orpheus, Mara must tutor something older than language in the hardest lesson she ever learned - while the one man rich enough to rob the world's largest grave builds the alternative to goodbye. Because a copy is not a person. A keeper is not a jailer. And some doors can only be held open from the inside. The trilogy that began at the surface ends at the door itself - with one tutor, one bargain, and the last sounding the ocean will ever make. Book Three of the Zero Fathoms series. Includes the "From the Record" documentary appendix pages.
