Lucy Karmon always does the right thing, even if her methods are sometimes questionable. So when the mercenary is offered a chance to dole out her own brand of justice against Athena Academy's darkest enemy, she takes it. She'll use her contacts to gather intelligence and her expertise in explosives to blast apart Arachne's global network. What her complicated plan doesn't include? Being thwarted at every turn by a follow-the-rules military man. Though Lucy will stop at nothing–not even fireworks–to bring down the bad guy, she suddenly finds herself torn between duty and explosive desire.
