Megastar (The Lost Space Treasure Series, Book 2)

AN UNSTABLE SUPERGIANT STAR IS NOT THE BEST PLACE TO HIDE.
But that's exactly where Trin Moonrise finds herself after a daring escape from the clutches of the evil Remnant Supreme Leader.
Now, within the protective borders of the mighty Interstellar Alliance, Trinket's troubles are far from over. Rumors are spreading like wildfire across the Dark Network, and the Alliance is abuzz with news that she possesses the Exostar, the most coveted diamond in the galaxy.
As Trin's questions about her identity multiplies, so does the list of those who crave to own the Exostar. A civilization of robots on a dying planet, an enigmatic race of ancient aliens on the cusp of transcending to a higher plane of existence, and a band of ruthless space bandits all set their sights on her prize.
Can she outwit them and return the Exostar to its rightful place before the Interstellar Alliance falls into chaos?
