When a deadly bomb goes off during a climate change debate, librarian and event coordinator Jackie Santoro becomes the prime suspect. Her motive, according to Detective Avery Wick: to avenge the suicide of her prominent father, who was accused of crimes by a city councilman attending the event. He can't exonerate her even after an extremist group takes responsibility for the bombing and continues to attack San Antonio's public spaces. As Jackie proceeds with plans for the Caterina Ball, the library system's biggest annual fundraiser, she fears the event provides the perfect opportunity for the bomber to strike again. -- adapted from back cover
