What is the author's style in Assassins by Tim F. LaHaye?

The book is written in straight-forward language with an acceptable mix of narrative and dialogue. Both narrative and dialogue are used to help clarify points that may be confusing to the reader who hasn't had the benefit of previous books and would refresh the memory of the reader who read previous books at some point in the past. For example, the book opens with an introduction of Rayford Steele. Though Rayford has been a main character in previous books, this introduction would be important for a person who doesn't have information about previous books of the series.
