Secret Seven: The Secret Seven: Book 1
We loved this book! I didn't read famous 5 and secret 7 as a child thinking they were a bit old fashioned so neither of us knew what was going to happen next. My son did get a bit scared at one point, so I had to look ahead and promise him that all would be OK. This book is utterly charming. We have book two out of the library and book 3 on order. Loved it, and I was wrong. Its not old fashioned, just a jolly good read.
