Showing Under the Northern Lights by Tracie Peterson

Bestselling author Tracie Peterson continues her saga of life and love in the rugged Alaskan Territory with the second volume of the ALASKAN QUEST series. When Pinkerton agent Helaina Beecham's obsession with capturing a dangerous fugitive dulls her judgment, she is kidnapped and carried off into the wilderness just as an early winter is approaching. Now her only hope is that Jacob Barringer--the man who has captured her heart--will find her before it is too late.
