This prequel to Practical Magic was released two Halloween Bingos ago, and I had planned to read it then, but didn't want to spend the $12.99 to buy it for my kindle, and the library list was dozens of holds long so I back-burnered it.
While I was casting about for something to read for the Spellbound square, I remembered that I had wanted to read this, so I looked on library2go and lo and behold, it was available without a wait. Downloaded at 5:00, finished at 8:30.
I really enjoyed it, and returning to the world of the Owens clan was delightful. It's been years since I read Practical Magic, or anything by Alice Hoffman, and I was reminded by The Rules for Magic how much I enjoy her story-telling and her use of magical elements.
This book will fill many squares as well, and I decided to use it for Relics and Curiosities instead of Spellbound, since it is generally easier to fill broader squares versus narrower ones. There is a grimoire that plays a prominent part of the book, which fits with the category. In addition, there is a Black Cat named Wren, for anyone looking to fill that square. There are also some events that occur on Halloween, so it would satisfy that one, and, off the top of my head, it would also fit Full Moon, Sleepy Hollow, Fear the Drowning Deep, and Magical Realism.
