The Arthurian legends have inspired countless tellings and retellings though few of those have been for children. Nancy McKenzie corrected that a couple of years ago with Guinevere’s Gift, intended to be the first book in the series she is calling the Chrysalis Quartet. Guinevere’s Gamble (Alfred A. Knopf) is the second book in that series.
The strong female heroine in this series is likely to make this a book favored by girls aged 10 to 14. As Booklist said, this series puts a “feminine spin on a tale more typically focused on men.” And though Guinevere’s Gamble is the second book in the series, you will understand what’s going on with no trouble if you’ve not yet read the first one.
