If you already know who the main characters are, you might enjoy this story. I did not, and Sara Winters does not really introduce the characters to the reader. After completing the story, I would not be able to select any f the 4 main characters from a photo line up. I only have a vague idea of what they look like, and find I am not familiar with the personalities, either.
It could have been a good story, but the lack of character descriptions has severely crippled the impact.
