Last week my older son asked me to choose a book for him as he wasn't going to be with me. I was wandering the aisles and nothing was grabbing me, so I sent up a quick thought: "Lord and Lady, lead me to something suitable that he would enjoy." I walked about another three steps, and the book "Lob" by Linda Newbery caught my eye. I flicked through it, and was amazed at what I'd been directed to. A story of a young girl and her grandad, wherein he tells her all about "Lob-Lie-By-The-Fire", and how only special people could see Him. I won't give any more away, but I will say that even though it is geared to 7-9 year olds my 11 year old devoured it and is re-reading it now!
I'm not sure if it's ok to post links so I wont, but if you'd like a link the the authors page let me know. (Or you can certainly just Google. )
