You can't beat a traditional children's story and 'The Velveteen Rabbit' (or 'How Toys Become Real') is no exception. Naturally it helps that it is about a cute little toy rabbit that wants to be a real rabbit!
Written by Margery Williams, it was first published in 1922 and remains a children's classic, not least because of the endearing depictions of the bunny in question by illustrator William Nicholson.
I've discovered a lovely true-to-the-original version of the book here which you (or your kids!) can read online, complete with beautiful illustrations. There is also a PDF version of the book available from the www.archive.org website.
