For more than two centuries, five werewolves have secretly served every American president since George Washington. Their names have never appeared together in an official record, and the country they protect has no idea they exist.
Fourteen years after their last mission tore them apart, the pack is called together again.
Federal agent Julia Serrano is sent to a guarded estate outside Madrid to protect a young boy and investigate a threat no one else believes is real. When the boy is kidnapped, Julia’s reports disappear, her own government abandons her, and the conspiracy she uncovered reaches far beyond Spain.
Gideon expected the president’s call to lead him to another mission. He did not expect to find a wounded agent who refuses to remain behind, challenges every decision he makes, and awakens a bond his wolf recognizes before either of them is prepared to accept it.
As Gideon reunites the pack he once scattered, Julia must decide whether she can trust five dangerous men who operate beyond the law and carry a secret that could change everything she believes. Together, they must rescue the missing boy, expose the traitor hiding inside the government, and stop an enemy willing to destroy anyone who discovers the truth.
Because when every system fails, they are the last line.

The Last Layer is the first book in The Last Line, a paranormal romantic-suspense series featuring covert missions, political conspiracy, found family, true mates, and five nearly forgotten wolves returning to the fight.
