The Dark-Eyed Shaman [EPUB ebook] 

In the aftermath of Sasha and Jayhan’s rescue, King Gavin learns of an upcoming invasion to Carrador.
Upon return to Highkington, eleven-year-old Sasharia and her elder brother, Jondarion, try to settle back into day-to-day life. But Toriana, the murderous aunt who killed the rest of their family, has no intention of allowing Sasha or Jon to survive, and will go to any lengths to protect her throne.
Setting out for Kimora, the two hold on to a faint hope that Sasha, by wielding her amulet, can overcome her aunt’s magical binding and confront Toriana herself. But even with the help of her companions the task is monumental for a young girl, whose own undeveloped power is still raw and unwieldy.
But Sasha is the true High Shaman and holder of the dark amulet. She is the only person who can even attempt to stop Toriana before the Kimoran armies invade Carrador. And unknown to them all, another unexpected force is also in play.
