BEACHES by James Loscombe is one of the most emotional end-of-the-world stories I've ever read. Essentially, a young man travels for six months to find out what happened to his family, after a virus wipes out most of the world's population. (No zombies, no warfare, just a swift death.) The only ones left are the ones fortunate enough to have a natural immunity.
He's been haunted by nightmares because he didn't search for his family sooner. Instead, he helped build a community of survivors. Finally admitting to himself, his need for closure, he sets out for his parents' home. He thinks he knows what he's going to find, but he couldn't be more wrong.
Very well-written drama.
