Paris. August. One long summer of nothing. 48 hours of everything. From the inimitable Meg Rosoff comes a chaotic and irresistible new YA. 17-year-old Callum is facing an unfortunate truth: his summer exchange in rural France was a failure. No epic adventure, no summer fling, and his French is still rubbish. Just as he should be boarding the Eurostar home, without even a hint of a plan, Callum impulsively decides to stay (and doesn't bother telling his parents). He only knows one person in Paris: his long-lost cousin, Harrison, an oboist. As night falls on the hottest weekend of the year, an adventure begins - involving a motorbike, a curfew, a stolen oboe, a priceless Matisse painting, at least one police chase, a climate protest and the enigmatic, alluring, irresistible Lilou ... A completely delicious, funny, fast-paced summer read from the multi-award-winning author of How I Live Now , The Great Godden and Friends Like These .
