Things that I liked - the way that a lot of natural history was woven into the story was well done and there are some lovely descriptions of animal behaviour - I especially liked the information on hares and the phases of the moon. It's just in places it felt overwhelming - too much description and not enough actually happening.
"Few things feel worse than helping search for someone who's got lost..."
"The world doesn't stop when something terrible happens."
I also loved how in places you had to read between the lines to see the truth of what's happening, for example when the deer talked of what they believed happened to the wolves - you are in a position of knowing but they are not and I think that added a needed depth to the story. (Bearing in mind that this story is set in the UK and we currently have no wolves - the deer are not completely convinced).
I feel the recommended age range (9-12 years) may be slightly high due to the style of the story but I think younger children would either need help reading or have the story read to them.
At the end of the book there are some nice extras - Watching the Wild World which covers things to look out for from March to August, and a list of things to watch; things to do and things to read.
(I received a free copy of this book to review.)
