Query: Warwick Castle book

This is a book about the history of Warwick Castle from the time it was first built about a thousand years ago. I had purchased this book previously when I visited the castle in England, but it was destroyed. I finally found a new one. It is chuck full of historical facts like names and dates on a timeline, along with a detailed narrative. Even if I had not been to the castle, this is so very well and clearly written that anyone could enjoy it, especially history buffs. There are also many beautiful pictures, as well as some early drawings of each stage of the castle during its building process to what it has become today.
