Now, solve this: Review: Fun book. Young boy, 10, is given a toy castle by his nanny who is leaving to go back to England. The boy, William, is very upset that Mrs. Phillips is leaving. When he discovers that the castle, or more accurately, the Silver Knight that comes with it, is enchanted, he devises a plan to keep her with him. And thus begins a very satisfying tale of fantasy and heroism.I listened to the audio version of this book - read by the author along with an entire cast. I can't say it was the best audio book I've ever listened to. As often is the case, the reading by the author, while interesting, wasn't great. And it wasn't just the author. I often kept thinking to myself that I wish I had opted to read this one instead of listening to it.
Polarity: Negative
Solution:
False
