Alex, Sandy and Lexie are summoned, because of powers of which they are not yet aware, to help in the fight of a threat against the world by the Darksiders. As they live far apart, in different countries, they meet initially via the Internet, and their mobile phones, but more supernatural meetings also take place. They explore their own powers and the powers of nature, and utilise both in their efforts against the Darksiders, efforts which are directed by other, older Light-Bringers, one of whom acts as their 'guardian angel'. Combines history and the present day, myths and Web 2, technology and science, with fire, water and maybe magic. http://marijsak.googlepages.com/thestonesummons
