Query: Not What I Expected

Unfortunately, I did not read the previous books in this series. That being said, I had a hard time following the story line(s) that were in the book. I read 287 of the 346 pages, and am undecided if I want to finish. I thought the main characters were Antonia Stonewright and Michael Langton (as suggested on the back cover), but I have learned more about characters apparently introduced in the previous books than I have Antonia and Michael.I highly recommend reading the previous books in this series before starting on this one. Fortunately I got this book at the library, and did not pay for it.
