I'm a homeschooling mother and this is one of my family's favourite series of all times. While the kids are kept entertained by the unpredictable goings-on, there's a great dose of healthy, adult-style humour to keep parents turning pages too.
There are two plot threads converging together in this first book.
For the first time in several years, children want to march in a special, huge parade celebrating the birth of a local legend. They are anxious to build the biggest, most impressive float to convince Mr Winkel, the antagonistic organiser, that they deserve their spot. It's a massive, built-to-scale replica of the Moodey Building, where they all live and the famous celebrity was born.
During their hard work, somebody walks past, glances at the plans and predicts that the tower will surely topple during the parade. It's Yakov Plonsk, the strange, new foreign boy who keeps himself aloof from the other kids, as they tease him and call him the Yak. Only Hazel Green has a niggling feeling that they shouldn't dismiss the Yak's predictions, as she knows he has a brilliant mathematical mind. But if she demands to know what he means, will she even understand his explanation, let alone have a chance of convincing the other kids that they need to avert a potential catastrophe?
Hazel has also been accused by her favourite baker, Mr Volio, of betraying him by leaking information about a new, delicious cake, to the rival bakery. It seems only the Yak will be able to help her prove her innocence and catch the real traitor. But she has to tread carefully with him and give him a good reason to believe that she genuinely wants to be his friend. He has had plenty of reasons to be sceptical in the past. The range of wonderful cakes and pastries Mr Volio makes always made us hungry enough to want to stock up on danishes and eclairs while reading the story.
This really set us up to want to get hold of the other books to find our what the impulsive Hazel and reflective Yakov have to solve next.
