What's it's about:
Career Day at Guadalupe Middle School: a day given to innocent hopes and youthful dreams. A day no one in attendance will ever forget.

New York Times bestselling author Laurie R. King is an award-winning master of combining rich atmospheric detail with riveting, keen-edged mystery. Now, in her newest standalone novel of psychological suspense, King turns her sharp eye to a moment torn from the headlines and a school under threat.
A year ago, Principal Linda McDonald arrived at Guadalupe determined to overturn the school's reputation for truancy, gang violence, and neglect. One of her initiatives is Career Day--bringing together children, teachers, and community presenters in a celebration of the future. But there are some in attendance who reject McDonald's bright vision.

A principal with a secret. A husband with a murky past. A cop with too many questions. A kid under pressure to prove himself. A girl struggling to escape a mother's history. A young basketball player with an affection for guns.

Even the school janitor has a story he dare not reveal.

But no one at the gathering anticipates the shocking turn of events that will transform a day of possibilities into an expolsive confrontation.

My thoughts:
3.5 stars
It was a little confusing and left some unanswered questions . With that said I would like to think NetGalley for giving me the chance to read it in a change for my honest opinion.
