The sequel to Wolves of Willoughby Chase, and even better than Wolves. We galloped through this book, because we all loved it. A few of my girls (I think each literate one) read ahead, in spite of strict warnings not to.
I know now why I knew the name Dido Twite even though I hadn't read the book. She's quite the character.
The adventures in Black Hearts are more wildly improbable than the adventures in Wolves. I think we liked the book better because there's an element of mystery added to the adventures.
I must be sure to speak to my husband about adding a large tapestry to our survival kit. ;-)
I highly recommend this book to YA or juvenile fiction readers. I think it would appeal to boys as well as girls, though I only tested it on girls.
