Rookie anthropologist Emily Radsco has come to the Colorado mountains to investigate old and mysterious carvings on aspen trees. She soon finds herself at odds with the local logging industry. If she doesn't work quickly, she'll lose the very trees which hold the clues to the riddle she's trying to solve. Complicating matters is her increasing attraction to soft-spoken Hopi, Mason Hitapwa, one of the loggers endangering her research. Romance isn't part of Emily's academic agenda, but she can't ignore her feelings as she and Mason uncover one of the forest's oldest secrets. The secret changes their lives forever, hinting that what they are experiencing has happened before: Love repeats itself, moving in echoes from one era to another, from one heart to the next.
