When Mary Beth McIntire settles into a vacation house on June 2, 2017, she anticipates a quiet morning with coffee. Then she hears a noise, peers out a window, and spots a man in 1950s attire standing in the backyard. She panics when the trespasser sees her and enters the house though a door to the basement. She questions her sanity when she cannot find him. In the same house on March 21, 1959, Mark Ryan finds a letter. Written by the mansion’s original owner in 1900, the letter describes a basement chamber, mysterious crystals, and a formula for time travel. Driven by curiosity, Mark tests the formula twice. On his second trip to 2017, he encounters a beautiful stranger. He meets the woman in the window. Within hours, Mary Beth and Mark share their secret with her sister and his brother and begin a journey that takes them from the present day to the age of sock hops, drive-ins, and jukeboxes. In CLASS OF ’59, the fourth book in the American Journey series, four young adults find love, danger, and adventure as they navigate the corridors of time and experience Southern California in its storied prime.
