You might want to wear some flowers in your hair, because this book will take you to San Francisco, 1968! The book is peopled with Black Panthers, hippies, and poets of the revolution. But it's not so much a book about history as it is a book about three sisters having a summer adventure, meeting new friends, and forging a relationship with the mother who abandoned them several years earlier. I recommend this book for tweens, teens, and adults--everyone will get something out of it. It's especially good for poetry-lovers, since poetry plays an important part in the story.
