When Luma Dewan wakes up on the morning of her seventh birthday, she knows that today will be special. But she has no idea just how wonderful and extraordinary it will be. For today is the day she will meet Timir, a real talking dragon. Or at least when Luma is around that's what he is. When anyone else is there, he becomes an ordinary grey puppy with a fluffy tail, who loves chasing squirrels and bouncing on trampolines. It's a big secret to keep and Luma's clever cousin Arjun is soon suspicious of this peculiar puppy, who doesn't quite behave like any other dog. Luckily Luma's grandmother - Nani - is there to help, and to Luma's surprise, Nani might just know a little dragon magic of her own . . .
