I really like how Black, doesn't put the LDS them heavy in her books. The LDS views are in her books, but she isn't preaching to the readers.
Over all I do like this book, but I do think that 3.3/4 stars should be an option.
Ester is living with the killer, you'd think she'd know who killed Olivia. The younger sister Ester in her own way was trying to help her sister, but manage to get herself into trouble.
As for Catherine's character, wow, she was going crazy there at the end. She couldn't think straight. When you'd think Catherine's character would get things right, she'd just dismiss it. At the end she was questioning almost everyone she meets.
Then the collage roommate Danielle. I think that Danielle is Blacks best antagonist yet. She was the embodiment of cool, collective, organized, very respective, with a dark side, very dark side that only Ester knew about, but Olivia figured it out by accident. It made you question who was trying to help who?
