This is a cute Christmas story about a little (young) elf who wants to be grown up. He sneaks back in to the toy room when the grown-ups have gone, in order to prove his grown-up abilities. Needless to say, the results aren't exactly as planned. Our dear little elf must decide - stay and fess up to the problems or run. Which does he pick? What are the results? Let's just say Santa *always* knows who has been naughty or nice.
The book does have some cute pictures, but is certainly not predominantly pictures. It is an appropriate length, and of light enough content to make a pretty good bedtime story. I'd guess a 4 to 5 year old would be the best age range for the book.
Text to speech: if you are used to listening to the TTS it isn't bad, but there are a number of places where backquotes are used and the TTS voice says the word "backquote" each time. That might be distracting to your younger listeners.
