This is the kind of middle-grade fiction that reminds you why the genre exists. Katherine Rundell has a genuinely distinctive voice, and the premise—rooftop-dwelling children, a baby surviving a shipwreck in a cello case, a search for an 'almost impossible' mother—is pure magic.
The book delivers on its promise: it's hopeful, thrilling, and imaginative without being saccharine. Sophie is a great protagonist, the Parisian rooftop world is evocative, and the themes (never ignore a possible, chosen family, resilience) land without being heavy-handed.
The violence is worth noting—Common Sense Media flags it specifically, and it's more graphic than you might expect (lost limbs, vicious fights). It fits the street-urchin setting and isn't gratuitous, but parents of sensitive 8-year-olds should know it's there.
Overall? This is a strong, well-loved middle-grade adventure that holds up. Not a modern classic that'll be read for decades, but a very solid pick for kids who love whimsy, adventure, and believing in the impossible.
