I picked up 8 books in this series cheap at a used bookstore. They look good. They're Christian mysteries. I have nothing against that but I don't know why I never much care for books written by this author. Maybe I didn't like this book because it's about tennis? I'll certainly try another one, though. One thing that annoyed me is that there are 90 very short chapters in the book. The book is narrated chapter and chapter about by twins Bryce and Ashley Timberline. I was never sure, or remembered, who was the voice for that chapter and had to keep going back (only 1 page but still....) to see which one was speaking. Although they're boy and girl twins they're almost one person and I really didn't get to know them as persons. Another thing, although I have not read the 6 books prior to this one, it alludes to "new evidence" that surfaces regarding the plane crash that killed their father. Unless I was sleeping during that part, I really didn't think what was told was much in the way of new evidence- just confusing.
