Forever in Blue: The Fourth Summer of the Sisterhood by Ann Brashares

As another summer begins, four lifelong friends — Lena, Tibby, Bridget, and Carmen — find themselves standing at the uncertain edge of adulthood. The jeans that once symbolized their unbreakable bond still travel between them, but life is beginning to pull them in different directions.

Lena is torn between her art and a love she thought she’d left behind. Tibby wrestles with her fear of vulnerability, learning how easily one moment can alter everything. Bridget seeks stability in a world that thrives on change, while Carmen discovers how difficult it is to define herself outside the lives of others. Across cities and continents, the threads of their friendship stretch and strain, testing the strength of what they’ve built together.

Ann Brashares closes her beloved series with quiet insight and emotional clarity. Forever in Blue is not only a story of growing up, but of learning that true connection endures — even as time, distance, and circumstance reshape the lives it touches.
