The Memory Tree: Carson Chronicles, Book 2 (Unabridged‪)‬

Days after barely escaping 1889 with their lives, the Carsons, siblings from the present day, resume their search for their missing parents in 1918. While Adam and his pregnant wife, Bridget, settle in Minnesota, unaware of a wildfire that will kill hundreds, Greg seeks clues in his great-grandparents' Mexico, where he finds love, danger, and enemies. At the same time, Natalie, the ambitious journalist, follows a trail to World War I France, and teen twins Cody and Caitlin rekindle a friendship with an old Pennsylvania friend haunted by her past. 

In The Memory Tree, the sweeping sequel to River Rising, several time travelers find answers and meaning as they continue the adventure of a lifetime in the age of doughboys, silent movies, and Model Ts.
