An exquisite, thought-provoking book to help children understand the idea of ever-changing emotions.   Rowan loves the river; it's just like he is. On some days, it's quiet and calm, on others it's light and playful, and then there are the days when it roars along, wild and angry. But when Rowan goes through a particularly difficult winter, the river freezes - just like Rowan. Can Rowan find a way to release his frozen feelings, and allow the river to flow freely once more?   The wise and reassuring new picture book from the creator of The Invisible and Ruby's Worry.
