The hero of our story loves his birthday present: a plant he names Ivy. But little does he know, Ivy is a high-maintenance sort of plant, one who requires special daily attention, and has a secret appetite for mischief. On Monday, our hero asks his sister to keep an eye on Ivy while he is out, but he arrives home and - where has his sister disappeared to? The next day he must ask Grandfather to look after the plant, but he vanishes too, as does Granny when she watches Ivy on Wednesday. Throughout the week the house becomes more and more empty, while Ivy continues to fill it, thriving and growing bigger each day...what is going on here? The mystery is solved with a surprise pop-up that reveals all! Full of twists and humour, this delightfully illustrated book by internationally renowned author Barroux will captivate young readers, while helping them to learn the days of the week in a fun and novel way.
