"That action is persistent and intense. In turn suspenseful and absorbing, this thriller features an elaborately developed protagonist and a setting in Boston that is vividly written."

Readers love this "fantastic debut novel" that they find "gripping, enthralling, immersive", with, "a page-turning plot and characters you want to hang out with woven into a shockingly possible 'what If' scenario".

The Boston Marathon bombing was a one-time, random act of terrorism by a couple of disaffected brothers.

Or was it?

Former Delta Force operator and current private investigator Finn Koenen reluctantly agrees to take on a client who wants him to investigate a case the police (and Feds) already solved. But when a tantalizing clue from an unreliable witness suggests another, much more terrible strike is imminent, he finds that now he sounds just as unhinged as his obsessed client.

With time running out, will Finn uncover the truth in time to prevent the deadliest attack ever made on American soil?
