Jumble Wood (Hardback) by Helena Covell

Far, far away there was a wood. A jumble of twists and turns, ups and downs, and unknowns. The little creatures that lived thereeach had a thing that made them happy...

all of them except Pod, who just can't seem to find hers. Exasperated and sad, Pod sets off to discover where her 'happiness' might be hiding, only to find it in the friends she meets along the way.
