Tina never worries about being ‘ordinary’ – she doesn’t have to, since she’s known practically forever that she’s not just Tina Mains, average teenager and beloved daughter. She’s also the keeper of an interplanetary rescue beacon, and one day soon, it’s going to activate, and then her dreams of saving all the worlds and adventuring among the stars will finally be possible. Tina’s legacy, after all, is intergalactic – she is the hidden clone of a famed alien hero, left on Earth disguised as a human to give the universe another chance to defeat a terrible evil. But when the beacon activates, it turns out that Tina’s destiny isn’t quite what she expected. Things are far more dangerous than she ever assumed – and everyone in the galaxy is expecting her to actually be the brilliant tactician and legendary saviour Captain Thaoh Argentian, but Tina is just Tina.
