Undermountain (The Undermountain Saga, Book 1)

The Undermountain Saga

Perfect for fans of YA science fiction. A group of teens embarks on a backpacking adventure, each wanting an escape from real life, each for a different reason. For Danny it’s his mother’s domineering boyfriend; for cheerful Breyona, it’s a suppressed memory; for Shiv it’s a tragedy he keeps secret; for Wa it’s a chance to meet girls.
They have no idea that their hiking trip will take them farther from home than anyone has ever gone before!
