I think this book is interesting and you get into the book quite quickly, just like most other Jaqueline Wilson books. It is about a worry website that the teacher, Mr Speedy, makes. Each chapter has a new pupil in Mr Speedy's class write about their problem, whether it's at home or at school. By the end of each chapter the child's worry has been solved or is getting better.
One or two of the chapters are quite boring, like a girl called Claire's worry, but most of them are interesting.
This book isn't rude or that upsetting, so I would recommend from ages 8+.
