This award-winning debut explores what it means to be alive. Suzy cannot accept that things just happen. She thinks about many things: the sleep cycle of snails, the annual number of jellyfish stings, or how old you are when your heart has beaten 412 million times - just 12 years. At that age, Suzy's friend Franny drowned in the summer, even though she was a good swimmer. Suzy must find out how that could happen. It is a long, enlightening journey in a world full of wonders, until she realizes that sometimes the only comfort is to accept things that cannot be changed. A poignant story of self-discovery and a profound look at our existence.
