In the span between the Great War and the Great Depression, Aiden Royce loses both family and fortune. He has nothing left but memories and regrets until a series of letters arrive; ramblings written by a familiar hand that nevertheless offer Aiden some important clues. Months later he's roaming the grounds of the crumbling Cebren Spa, a once posh destination, but now an empty shell of mystery and menace. One saving grace in this perplexity is the handsome Sebastian Desmond, a descendant of the spa's founders. He rescues Aiden from a storm, but in doing so opens up a different sort of tempest when secrets unravel and both men's lives are torn asunder. Can decades-old questions be answered, onerous mysteries solved, and a burgeoning and venturesome romance prosper in the shadows of a once restorative wellspring?
