Women Like Us by Jason Pomerance
Susan Jones, a brash and ballsy chef who hopscotches from one demanding restaurant job to the next, was barely in her twenties when she married and had a son, Henry. But after her marriage to Andrew fell apart, she ceded most of the raising of the baby to her mother-in-law, the very opinionated Edith Vale, a woman as formidable and steely as her stiff blond bouffant, the veritable helmet that helps her soldier through life. Now, after letting Henry drift away, Susan is determined to make things right. But just as mother and son seem to make headway after embarking on a cross-country road trip, things take a dark turn. When the family reconvenes in California, everybody must fight to find courage and humor in the face of a situation that threatens to change them all forever.
