The Polar Bear and the Dragon

The Polar Bear and the Dragon: Perilous Passage is the third book in Debbie Watson's fantasy series for middle-grade and young-adult readers. Thirteen-year-old Whitney and her best friend Edward, 14, have become vital members of Yagdi's elite Alliance formed to protect and defend the small world from an enemy's hostile takeover. The Alliance's powerful group has defeated Sylern and ended the war, but the creature fled before capture and remains well hidden. Although some fear his return, most Yagdians welcome the fragile peace.
The Alliance is anticipating a joyful homecoming when an eruption destroys their portal and launches Whitney and Edward into a confusing maze of tunnels. Lost somewhere between Earth and Yagdi, the teenagers discover their abilities have mysteriously vanished just as a young wizard named Patrick appears out of nowhere. Suspicious this intruder is to blame, they listen to his dire warning of an ancient wizard clan living in the shadows but aren't eager to accept his offer to help them escape. They sense Patrick has devious motives, but confronting wizards without their powers seems far more dangerous. Hoping they're not making a grave mistake, Whitney and Edward risk trusting the promises of what may be a scheming trickster.
