Hidden Treasure is the latest book by well-known adult fiction author Jessie Burton. The vibrant historical setting and attention to detail found in her adult works such as The Miniaturist is also at the core of Hidden Treasure. The story follows Bo, a young girl living in London towards the end of the First World War. When she discovers a jewel-encrusted sphere in the Thames, her friends and family urge her to sell it; however, Bo soon realises there is more to the sphere than its riches.

What follows is an adventure of magic and mystery as Bo and her new friend Billy race against time to work out the true nature of the sphere. The story is rounded out by a host of villains, some known, some hidden, who want to use the sphere for their own purposes.

There is a lot in this book for a wily reader to uncover and the way all the pieces come together is immensely satisfying. On top of it all, Hidden Treasure explores grief and the ways people handle losing a loved one. It is a raw but immensely heartwarming book. Perfect for fans of Katrina Nannestad and Amelia Mellor aged 10+.
