A lost treasure. A riddled quest. The healing power of friendship. Legends are tucked into every fold of the Colorado mountains surrounding the quaint town of Mercy Peak, where residents are the stuff of tall tales, the peaks are taller still, and a lost treasure has etched mystery into the very terrain. In 1948, when outsider Mercy Windsor arrives after a scandal shatters her gilded world as Hollywood's beloved leading lady, she is determined to forge a new life in obscurity in this time-forgotten Colorado haven. She purchases Wildwood, an abandoned estate with a haunting history, and begins to restore it to its former glory. But as she does, her every move tugs at the threads of the mountain's lore, unearthing what became of her long-lost pen pal Rusty Bright, and the whereabouts of the infamous Galloping Goose Railcar No. 8, which vanished years ago--along with the mailbag it carried, whose contents could change the course of countless lives. Not to mention the fabled treasure that--if found--could right so many wrongs. Among the towering mountains that stand as silent witnesses, the ghosts of the past entangle with the courage of the present to find a place where healing, friendship, and hope can abide amid a world forever changed.
