Cat Powell Novel- Spies We Know

LM Reynolds continues the gripping story begun in her award-winning novel Spies in Our Midst in this sequel of deceit, treachery, sacrifice, and heroism.
Fresh from averting a planned terrorist attack that would have devastated the city of Boston, an elite team with ties to three of the nation's most storied agencies remains on the hunt. While the plot's mastermind is now in custody, he has refused to name the others involved. With legendary intelligence operative Cat Powell and former ambassador Paul Marshfield at the helm, the team is on a mission to discover the identities of the coconspirators and bring them to justice.
With the only remaining lead pointing to a dormant e-mail address using the handle "Conrad27," the trail seems to have turned cold ... until an intercepted message reignites the investigation. Paul taps the expertise of Cat's half-sister--Lindsey Carlisle--and her team of accomplished hackers to join the chase. The discovery of a hidden cache of explosives points toward military involvement, and what begins as a gray-hat pursuit through the digital domain quickly turns deadly as the hunters become the hunted.
As mounting evidence leads to a shadowy group in India and to a Soviet agent formerly posted there, Cat has no choice but to unveil the truth of a prior mission. With the fate of an influential Indian delegation--and the Americans with whom they are meeting--in the balance, the team members find themselves in a desperate race to prevent the past and the present from colliding in tragedy.
