Boo said the Banshee
By Declan Carville & Kieron Black
Preloved, softcover book. 
Oollagh was a banshee who lied in a remote  part of Ireland. Home was underground, with the rest of her family. All 35 of them. But Oonagh was different to the others. She was afraid of the dark and hated the thought of going out to spook. Her mother was mortified, her Uncle Kevin was furious. Could Oonagh think of a way to keep everybody happy?
