She’s right. It can never happen again. She won’t let it.
Ten years have passed, and Ren Taylor is back at square one, having accepted a job at her old high school. She’d hoped to make peace with the past but now she’s thrust back into it: her murdered teenage sister is still immortalized in town, and Ren can’t stop seeing her wherever she goes. She’s dogged by the scandal that ruined her childhood and killed her sister. 
Then Ren meets physics teacher Bryson Lewis. Handsome and charismatic, all the other teachers and students seem to fall at his feet. But Ren knows men like him – she knows they can’t be trusted.
The more Ren watches him, the more suspicious she becomes. And when she notices his close relationship with a girl in one of his classes – a girl just like her sister – she worries history is about to repeat itself. This time, she won’t sit back and watch another girl be taken before her time.
This time, Ren will do what she must to save her, even if it means revealing her own darkest secrets.
