Prisoners of Thornbrill

A family enslaved
A tyrant rising
And they're not on Earth anymore
For five years, distrustful 20-year-old Melanie and her brother Jason thought the Grand Canyon would keep their dragon, Scalaed, safe. But none of that matters when all three wake up in another world as prisoners of the ruthless High Huntress, Helnah.
When a rebel hunter helps Melanie to escape, she must learn to trust him if she ever wants to get her brother and dragon back. Meanwhile, Jason uncovers Helnah's harrowing design for her human prisoners-a plan that makes him think twice about leaving the fortress.
If they fail to take down Helnah's dragon empire, Tindoria will burn to the ground with Scalaed at the helm. But to defeat the High Huntress, Melanie and her companions must wage war against the monstrosity dwelling in her volcano.
