Boston PI Spenser takes on a new case in this installment in Robert B. Parker's iconic New York Times bestselling series.

Carolina Garcia-Ramirez is a rising star in national politics, taking on the establishment with her progressive agenda. Tough, outspoken, and driven, the young congresswoman has ignited a new conversation in Boston about race, poverty, healthcare, and the environment. Now facing her second campaign, she finds herself not only fighting a tight primary with an old-guard challenger, but also contending with numerous death threats coming from hundreds of suspects.

When her chief of staff reaches out to Spenser for security and help finding the culprits of what he believes to be the most credible threats, Garcia-Ramirez is less than thrilled. Since her first grassroots run, she's used to the antipathy and intimidation women of color often face when seeking power. To her, it's all noise. But it turns out an FBI agent disagrees, warning Spenser that Garcia-Ramirez might be in real danger this time.

It doesn't take long for Spenser to cross paths with an extremist group called the Minutemen, led by a wealthy Harvard grad named Bishop Graves. Although Graves is a social media sensation, pushing an agenda of white supremacy and toxic masculinity, he denies he's behind the attacks. As the primary nears and threats become a deadly plot, it's up to Spenser, Hawk, and a surprise trusted ally to ensure the congresswoman is safe. This is Spenser doing what he does best, living by a personal code and moral compass that can't ever be broken.
