Finding Cadence by Joanne Huspek

Cadence Reed's world is shaken to dissonance after her husband, Carter, dies on an icy Michigan highway - along with his pregnant young girlfriend. His death reveals devastating secrets of a hidden life, leaving Cadie and her college-aged son with shaky finances. With her son, she begins a cross-country journey, one that not only ticks off miles, but self-examination. It's not just Carter's parallel life and indiscretions Cadie must wade through - in beating herself up over his choices, she discovers the compass guiding her own life is severely skewed due to secrets of her own. Thanks to old friends and new, Cadie finds a new rhythm for the rest of her life.
