Over the Mountain and Back — Marie Astor

After taking his new snowboard for a ride in the mountains of Colorado, Peter Bailey is stunned to find himself in Transadonia �" a hidden world that coexists alongside with the Earth.

Peter soon learns that the shiny, new snowboard was crafted especially for him by the smiths of Transadonia. Now, Peter's help is needed to defeat the evil mastermind who is threatening the freedom of Transadonia's magical inhabitants. Just why has Peter been chosen for this daunting task, and does he have the mettle to complete it?

Lara Grover never listened to her elders, so warnings like “do not talk to strangers” mean nothing to her. When a boy from an unknown world saves her from an avalanche with the aid of a snow dragon, Lara is not stunned in the least. Instead, she joins Peter on his quest to help him realize the purpose behind his arrival to Transadonia.

Together, Lara and Peter embark on an adventure filled with perils, trickery, betrayals, and unexpected alliances.
