Tanya… or rather, Tammy, my older sister—I only knew she existed, and that was all. She was “someone else,” I guess. And her daughter too. But Tammy was killed, and her daughters disappeared—lost somewhere in the USA. It would seem there’s no reason for me to care. But… There’s a stone called tourmaline. One stone, but dozens of variations. Red and black. Green and blue. Lilac and orange-brown. Pieces of this crystal can be so unlike each other that you’d never suspect they’re related. Just like my family. It’s not one single whole—it’s a set of completely different elements that somehow, in an unfathomable way, ended up connected. And now I have to find that connection—soon, because otherwise… something will happen. Something bad.
