The Last Witness. The Remaining series, #8

A climate scientist in his sixties becomes Antarctica's only human. After months alone with penguins and a failing greenhouse, he repairs an abandoned icebreaker and sails toward South America. He finds the Bolivian woman's wrecked raft on a Chilean beach - no body, just her parrot. He follows the bird inland, and the book ends with him realising he is no longer alone. Book 7 The last witness synopsis**Cape Town, South Africa - June 20, 2026****Zara Mbeki was thirty-nine years old when she woke up to an empty continent.**A former war correspondent turned wildlife documentarian, Zara had spent her life bearing witness - to conflict, to extinction, to the slow unraveling of the natural world.
She had survived kidnappings, gunfire, and the psychological toll of watching humanity destroy itself. She was not prepared for this. When the Vanishing came, Zara was in her apartment in Bo-Kaap, the colorful Cape Malay neighborhood overlooking Table Mountain. She had been editing footage of endangered rhinos when the world went silent - not gradually, but all at once, like a switch had been flipped.
She walked through the empty streets of Cape Town. She climbed Table Mountain. She stood at the edge of the continent and looked out at the Atlantic, wondering if anyone else was out there. She found no one. For weeks, Zara survived alone, documenting everything - the returning wildlife, the collapsing infrastructure, the impossible silence. She raided museums and archives, preserving what she could.
She broadcast on every frequency, desperate for a voice. But Africa was empty. All 1.4 billion people, gone. Then, on the forty-seventh day, she heard it - a faint signal from across the ocean. A woman's voice, speaking English, broadcasting from somewhere in Europe. Eleanor. Zara cried for the first time since the Vanishing. But her journey was only beginning. Africa - vast, wild, and utterly empty - held secrets that no one else could uncover.
Ancient ruins. Uncontacted tribes (or rather, the places where they had been). The last remaining populations of the world's most endangered species. And something else - something the other survivors wouldn't understand until they met her. Zara was not just a survivor. She was a witness. And she had seen what the Vanishing really meant.
