'Lucy is about to start high school. She has a cool new friend, Briony, and feels she's outgrown the school holiday 'Overseas Adventures Days' she shares with her grandfather, a retired Geography teacher. When Lucy asks to spend those days with Briony, instead of doing geography research and international craft and cookery with Gramps, her mother refuses and reveals a poignant reason. However, when an emergency threatens more than just Lucy's Fridays with Gramps, she reflects on all they've shared, and what is most important in her life.' (Publication summary)
