Serafina and the Twisted Staff is an excellent book about mystery, horror, and friendship as well. Deciding to read this book, along with the first book, Serafina and the Black Cloak, and two other adventures called Serafina and the Splintered Heart and Serafina and the Seven Stars. The book is for 9 - 12 year old girls and boys. We'd also recommend this book because it has around 14 points.
