Lowery has impressed me in the past, filling his family-centred stories with humour (Socks are Not Enough) and pathos, in stories that will pique the interest of primary-aged readers.
This novel features a wonderful pairing - brothers Martin and Charlie, a young teen and his younger brother who have, apparently, run away from home to travel more than 400 miles to Cornwall, where they are hoping to see the dolphin they saw on a family holiday.
Their determination is puzzling - just what significance does the dolphin hold for them? But they are resourceful in their lack of funds, Martin clearly adores his little brother, and Charlie has enough personality for a whole family of characters.
Their backstory is revealed through the course of the book, as they approach their destination, though many obstacles attempt to stall them - their parents, for example. Martin's poems also give us an idea of their family and history. The final reveal is quite a punch in the gut and incredibly sad - some readers may be quite upset (warning!).
A warm, chatty style of narration, Martin feels very real, loving and worried, and readers aged 10-14 will take to the story and their adventure from the start.
