River Rising by John A. Heldt

Weeks after his parents disappear on a hike, Arizona engineer Adam Carson, 27, searches for answers. Then he discovers a secret web site and learns that his mother and father are time travelers stuck in the past. Armed with the information he needs to find them, Adam convinces his younger siblings to join him on a rescue mission to the 1880s. While Greg, the adventurous middle brother, follows leads in the Wild West, Adam, journalist Natalie, and high school seniors Cody and Caitlin do the same in Johnstown, Pennsylvania. Like the residents of the bustling steel community, all are unaware of a flood that will destroy the city on May 31, 1889. In RIVER RISING, the first novel in the five-book Carson Chronicles series, five young adults find love, danger, and adventure as they experience America in the age of bustle dresses, gunslingers, and robber barons. Readers' Advisory: River Rising is the first novel in a five-part family saga that spans several decades. While some storylines are resolved, others are not. They are addressed in subsequent books.
