Once upon a very badly behaved time, 511-year-old Ebenezer kept a beast in his attic. He would feed the beast all manner of objects and creatures and in return, the beast would vomit him up expensive presents. But then The Bethany arrived …

Now ten-year-old notorious prankster Bethany, along with her new feathery friend Claudette, is determined that she and Ebenezer are going to DE-BEAST their lives and do good. But Bethany finds that being a notorious prankster makes it hard to get taken on for voluntary work. And Ebenezer is secretly missing the beast’s vomity gifts. And neither of them are all that sure what ‘good people’ do anyway …

Then there’s Claudette, who’s not been feeling herself recently. Has she eaten something that has disagreed with her?
