When Auggie Lopez returns to Wroxall College, he's determined that his second year will be different from the chaos he faced as a freshman. He's living in the Sigma Sigma house, he's got a good group of friends, and his social media presence is growing. Meeting a hot older guy on move-in day is just the cherry on top. All he has to do now is avoid getting dragged into another murder.

That last part, though, turns out to be easier said than done, especially when Auggie's ex-roommate, Orlando, asks for help. Orlando's brother Cal has gone missing, and Orlando wants Auggie to find him.

Auggie knows he'll need help, but recruiting his friend—and crush—Theo is not as straightforward as he expects. While Auggie was gone for the summer, Theo has started dating someone, and neither Theo nor Auggie knows how to handle the shift in their relationship.

Finding Orlando's brother dead only makes their situation more complicated. Although the police are quick to write off the homicide as a drug deal gone wrong, Auggie and Theo aren't so sure, and Orlando begs them to keep investigating. To learn the truth, Auggie and Theo will have to untangle a web of lies while keeping each other safe from a killer who is determined to stop them.

As Auggie and Theo dig deeper, they realize that Cal was a stranger even to the people who thought they knew him. And Auggie and Theo both begin to fear that they are also strangers to each other.
