And after spending time volunteering in a convalescent home she has just the idea on how to bring a spark of joy to their troubled days. But even in her sanctuary difficulties abound. From a sneaky book thief in their stacks to fellow librarian Jane's husband becoming injured in action to their stern local councillor Mrs Montague-Smythe who still seems to have it in for Delia . . . Can she ever find light in the darkness?
