Seventeen-year-old Riki is worried about school and the future, but mostly about his girlfriend, who has suddenly stopped texting him. But on his way to see her, he's hit by a bus and his life radically changes. Riki wakes up one hundred years earlier in Egypt, in 1915, and finds he's living through his great-great-grandfather's experiences in the Māori Contingent. At the same time that Riki tries to make sense of what's happening and find a way home, we read transcripts of interviews Riki's great-great-grandfather gave in 1975 about his experiences in this war and its impact on their family. Gradually we realise the fates of Riki and his great-great-grandfather are intertwined.
