Holly's dad is an explorer, having amazing adventures all over the world, while Holly is stuck at home with her mum, her baby brother and the dog. Now Dad's on a new expedition and he'll miss her tenth birthday. She's not happy - until she finds out that he's planned a special treasure hunt, just for her. She has ten days to complete ten tasks - some silly, some tricky and some downright terrifying.
Maybe life at home isn't quite so boring after all.
Holly's mum has had enough! She challenges Holly and her dad (and the dog) to survive in the woods for five days without screens - in fact without electricity! Holly's not sure she'll be able to cope, but then she bumps into Zeb, and things get more exciting - and much more dangerous - than Mum intended.
Dad's embarrassing behaviour becomes the least of Holly's problems. To save the day, she'll need to be braver and more resourceful than ever before.
