Dragon Slippers is the first of a (so-far) trilogy by Jessica Day George, who is perhaps better known for her Castle Glower (
Tuesdays at the Castle, etc.) and Twelve Dancing Princesses series. I've read several of the Castle Glower series, and also
Dragon Slippers and liked them all.
Slippers has dropped to $0.99 as part of the US Kindle Daily Deal for today (Sunday), which is includes 80+ science fiction books. I'm not quite sure I'd consider this science fiction and it's definitely YA, so I'm posting it here.
George's titles tend to be mediumly pricey when not on sale, so if you're interested, grab it...
