Eleven-year-old Clara is struggling to find the truth about her missing father and grandfather and her dead twin sister, but her mother refuses to talk. When Clara begins interviewing Georg Kominsky--her elderly neighbor--she finds that he is equally reticent about his own concealed history. Precocious and imaginative, Clara invents versions of Mr. Kominsky's past, just as she invents lives for the people missing from her own shadowy history. Her journey of discovery is at the heart of this beautiful story about unlikely friendship and communion, about discovering what matters most in life, and about the search to find the missing pieces of ourselves.
