Elizabeth and Nathaniel Bonner have settled into their life together at the edge of the New-York wilderness in the winter of 1794. But soon after Elizabeth gives birth to healthy twins, Nathaniel learns that his father has been arrested in British Canada. Forced to leave Hidden Wolf Mountain to help his father in Montreal, Nathaniel himself is imprisoned and in danger of being hanged as a spy.
In a desperate bid to save her husband, Elizabeth bundles her infants and sets out through the snowy wilderness and across treacherous waterways on the dangerous trek to Canada.

Torn apart, the Bonners must embark on yet another perilous voyage, this time all the way across the ocean to the heart of Scotland, where a destiny they could never have imagined awaits them….
