A história que este livro conta poderia ter se passado com qualquer pessoa: comvocê, por exemplo. Num livro como este, parece que a história se passa com a gente. Ficamos íntimos das personagens. Temos a impressão de que o que acontece nas páginas do livro acontece conosco. Cada um de nós vive apenas a própria vida, e, lendo histórias, novelas e romances pode fazer de conta que é outra pessoa, que vive outras vidas, pode experimentar outros pontos de vista.

A girl finds a photo of her great-grandmother as a child and makes an invisible friend out of it.
This one was strange, and not in a good way, really. It unintentionally read like a sad story about a girl with some form of schizophrenia, and the writing was clunky at best. ( )

Bel finds a photograph of her great-grandmother and begins to hear her voice. They have fun conversations until her great-grandmother decides to start telling Bel how to behave. Not a story I would read or assign. ( )
