This book is part of the Poppy Fields series and this set is excellent for youngsters that are into mysteries. After retrieving it back from my 10 year old cousin (who is lets say a reluctant reader) on a short loan, she surprisingly couldn't wait to tell me all about it. The plot is well thought out, and it keeps you turning the pages and guessing right until the very end. Would like to read more in the series.
I won't spoil it too much but just a brief blurb - Poppy's first adventure sees her on a remote Scottish island where the organisers in a trial week for a new outdoor adventure centre are dying one by one.
Very cheap book (all are in this series) and I can highly recommend this. I did have a quick read myself, and despite it not been my cup of tea, it was easy to see how those of primary school age many find it interesting and unpredictable. Recommended book.
