Across the Bridge of Ice — Ruth Fox

In 'The City of Silver Light', Keira Leichman spent the night lost in a wild snowstorm that struck Cassidy Heights. But what really happened that night? Not even Keira can be sure. What she does know is that she's been having strange dreams since the accident, and now she's stuck with a broken ankle and the possibility of never playing soccer again. That is, until she finds Jake's telescope, and is drawn across the Bridge of Ice to Shar.

Now Keira is marooned in the City of Silver Light with Daniel, Jake's younger brother, with no way to get home. But that is the least of their worries, for the secrets they discover in Shar are more dangerous than Kiera could ever have imagined. And the fate of both their worlds are in their hands.
