The Tillerman Saga by Cynthia Voigt

Four siblings left to fend for themselves after their mother abandons them struggle to reunite with family and build a new life, with the eldest assuming the role of caretaker while each child confronts loss, discovers strengths, and searches for belonging; through intimate, character-driven episodes set in small-town life, the books trace their coming-of-age journeys and explore resilience, loyalty, forgiveness, and the messy work of growing up.
