September Sky by John A. Heldt

When unemployed San Francisco reporter Chuck Townsend and his college-dropout son, Justin, take a cruise to Mexico in 2016, each hopes to rebuild a relationship after years of estrangement. But they find more than common ground aboard the ship. They meet a mysterious lecturer who touts the possibilities of time travel. Within days, Chuck and Justin find themselves in 1900, riding a train to Texas, intent on preventing a distant uncle from being hanged for a crime he did not commit. Their quick trip to Galveston, however, becomes long and complicated when they wrangle with business rivals and fall for two beautiful librarians on the eve of a hurricane that will destroy the city. Filled with humor, history, romance, and heartbreak, SEPTEMBER SKY follows two directionless souls on the adventure of a lifetime as they try to make peace with the past, find new purpose, and grapple with the knowledge of things to come.
