In Emily Colin’s exquisite debut novel, perfect for the fans of Kristin Hannah, one man’s vow to his wife sparks a remarkable journey that tests the pull of memory and reaffirms the bonds of love. Before Madeleine Kimble’s mountaineer husband, Aidan, climbs Mount McKinley’s south face, he makes her a solemn vow: I will come back to you. But late one night, Maddie gets the devastating news that Aidan has died in an avalanche, leaving her to care for their son—a small boy with a very big secret. The call comes from J.C., Aidan’s best friend and fellow climber, whose grief is seasoned with survivor’s guilt . . . and something more. J.C. has loved Maddie for years, but he never wanted his chance with her to come at so terrible a cost. Across the country, Nicholas Sullivan wakes from a motorcycle crash with his memory wiped clean. Yet his dreams are haunted by visions of a mysterious woman and a young boy, neither of whom he has ever met. Convinced that these strangers hold the answers he seeks, Nicholas leaves everything behind to find them. What he discovers will require a leap of faith that will change all of their lives forever. “Dazzlingly original and as haunting as a dream, Emily Colin’s mesmerizing debut explores the way memory, love, and great loss bind our lives together in ways we might never expect. From its audacious opening to its knockout last pages, I was enthralled.”—Caroline Leavitt, New York Times bestselling author of Pictures of You
