Her Pretty Face by Robyn Harding - 4 Stars (Rounded up)

[~*Kim*~]

"Frances Metcalfe is struggling to stay afloat.

A stay-at-home mom whose troubled son is her full-time job, she had hoped that the day he got accepted into the elite Forrester Academy would be the day she started living her life. Overweight, insecure, and lonely, she is desperate to fit into the Forrester world. But after a disturbing incident at the school causes the other children and their families to ostracize the Metcalfes, she feels more alone than ever before.

Until she meets Kate Randolph.

Kate is everything Frances is not: beautiful, wealthy, powerful, and confident. And for some reason, she’s not interested in being friends with any of the other Forrester moms—only Frances. As the two bond over their disdain of the Forrester snobs and the fierce love they have for their sons, a startling secret threatens to tear them apart—one of these women is not who she seems. Her real name is Amber Kunik. And she’s a murderer."

This was a pretty fast paced read and pulled me in from the beginning. I rated it 3 1/2 stars and rounded up. (view spoiler)[Mostly because I was waiting for something explosive to happen and it didn't. The ending fell flat for me (hide spoiler)]
It took a bit to put some of the characters into the places that they played in the story, but when they did fall into place it made more sense.
