Snowdance

In the 24th century, Earth's fragile alliances hang in the balance. On the alien planet New Horizon, a pioneering research team goes silent amid a sudden, brutal winter—and rumors of sabotage by unknown intelligences. With advanced tech faltering and tensions rising, Earth's last hope lies in the past.

Operation Hourglass recruits teens with the one thing modern society lacks: grit.

From colonial New England, 17th-century farm girl Patience Whately has survived war, loss—and worse. From the 19th century, Norwegian snow-sport prodigy Sondre Auverson knows how to navigate any blizzard. And from the summer of 1978, Lee Jarrett is equal parts courage and curiosity, armed with only a harmonica and a stubborn streak.

Joined by two young volunteers from the future, they must brave alien forests, strange snow, and a hostile wilderness with secrets buried deep beneath the drifts. Can five kids from across time out-think an alien world?

Adventure, resilience, and the power of unlikely friendships come together in this thrilling new addition to the Out of Time series by Allen Steele and Robin Orm Hansen
