Frost-Spire by Laurie Mahon

After claiming the first Orb, Princess Selina and her companions race to the icy peak of Mount Frost-Spire in search of the next. But the journey is treacherous. Something watches from the ice. Something stirs beneath the stone. When their mission takes a disastrous turn, the team must think fast and fight hard before the mountain becomes their tomb. Will Selina's strength, Felix's magic, and Ryfon's skill be enough to survive?
