This story is a good continuation of Grim's family. I would recommended reading the series before this book because it is an addition to past stories (definitely read Grim and A Grim Holiday). This was more about Grim and Lisa's two daughters. They found an injured bird only spoken about in legendary stories and nursed him to health. The Raptor acknowledged them by giving one a feather of honor and the other an eye of the Raptor for the ability to sense evil.
