Major Leah Morgan is a tactical genius and fearless leader who's about to have her limits tested, in more ways than one. The major is tasked with leading the Legacy Operations Command (USLC) to confront supernatural threats from America's past. Her first mission takes the team to Boston's Old North Church, where a Revolutionary War-era mummy is about to awaken. A vital relic has been stolen, and Leah must lead her team into the hidden vaults of history to recover it before the undead spy rises again. Armed with a mix of historical knowledge and cutting-edge military tech, Leah takes command of a dangerous situation, while unresolved feelings for her second-in command, Jamie, simmer beneath the surface. The stakes grow higher as Leah faces an enemy long thought dead and a mission that could define her career. She must not only fight the enemy but confront her own past with Jamie by her side. The countdown begins--Leah has to stop the mummy before it wreaks havoc on modern-day Boston and brings a secret society out into the open.
