Rebirth by Kamal Ravikant

After the death of his estranged father, Amit takes his parent's ashes to the Ganges to fulfill a deathbed promise. Instead of returning home, he wanders, his pain and grief leaving him confused about his future. Almost broke, unsure about his direction in life, and running from memories, he is led by fate to the Camino de Santiago, an ancient 550-mile pilgrimage route across northern Spain.
