The Windvale sprites - Mackenzie Crook

When a storm sweeps through the country, Asa wakes up the next day to find that his town is almost unrecognisable - trees have fallen down, roofs have collapsed and debris lies everywhere. But
amongst the debris in his back garden Asa makes an astounding discovery - the body of a small winged creature. A creature that looks very like a fairy.

Do fairies really exist? Asa embarks on a mission to find out. A mission that leads him to the lost journals of local eccentric Benjamin Tooth who, two hundred years earlier, claimed to have discovered the existence of fairies. What Asa reads in those journals takes him on a secret trip to Windvale Moor, where he discovers much more than he'd hoped to . . .
