Marine Captain Luke Steele and FBI Special Agent Amberlyn Reiner must work together to unravel a deadly conspiracy before time runs out while also navigating their undercover fake relationship that is becoming all too real. 

When a terrorist attack grips the nation, Luke Steele, a military aide to the president of the United States, is reassigned to track down the suspect because the alleged bomber was spotted wearing a state championship ring from Luke’s hometown. Luke has desperately tried to forget his high school years, but he can’t run from them now. Instead, he must face his most formidable assignment yet: leave his post by the president’s side, return to Pine Falls, Virginia, and face every demon from his childhood—including every person and every thought that told him he wasn’t worth anything.  

FBI Special Agent Amberlyn Reiner has spent years tracking domestic terrorism. When she catches a break that could pinpoint the key player in the antigovernment group responsible for dozens of needless deaths, she’s willing to do whatever it takes to get the information she seeks—even if it means going undercover as Luke Steele’s plus-one at his high school reunion. Though Amberlyn found Luke arrogant and aloof during their time together at Quantico, it doesn’t take long for her to discover that there’s much more to him than she realized. But even as the line between fact and fiction in their relationship blurs, the countdown to danger accelerates. Time is running out, and with the threat of another terrorist attack looming, the stakes are higher than ever.
