Nothing new about the book except for the cover, which looks awesome! The official summary is below:
On the planet Tython, the ancient Je’daii order was founded. And at the feet of its wise Masters, Lanoree Brock learned the mysteries and methods of the Force—and found her calling as one of its most powerful disciples. But as strongly as the Force flowed within Lanoree and her parents, it remained absent in her brother, who grew to despise and shun the Je’daii, and whose training in its ancient ways ended in tragedy.
