The illustrations in this are gorgeous, absolutely gorgeous.
I'd read or heard of most of the stories in this charming book, and I particularly liked the re-tellings of the ones more local to me.
I wouldn't say this is for really young children, perhaps 6+. It feels a bit grown up in places and younger children would probably struggle to understand some of the terms. It'd be perfect for reading aloud, perhaps a bedtime story to inspire dreams of dragons and giants?
