The Frozen Kingdom, book 1

On a frozen planet locked in eternal winter, Galatéa, a princess and warrior in the making, trains to master her growing powers. Young and a little naive, she is suddenly thrust into an unknown world, left to fend for herself. But when war erupts, led by a ruthless enemy commanding an army of Shadowchanters whose powers defy reason, her world is thrown into chaos. She soon realizes that her choices could save thousands of lives... or doom them all. As darkness spreads, Galatéa must face her fears, uncover the truth about her origins, and decide whether she is ready to bear the weight of an entire world on her shoulders. For no matter how hard she fights, danger is closing in...tightening like a vise.
