Homeland Insecurity

From USA Today and Amazon bestselling author Shawn M. Warner (Leigh Howard and the Ghosts of Simmons-Pierce Manor)
"Jack and his crew have the makings of exemplary secret agents-they're whip-smart, plucky, compassionate, and most assuredly able to carry a series." -Kirkus Reviews
Secret agents are all Jack and his friends ever wanted to be. Spy adventures were the movies they watched, the books they read, even the games they played.
Playtime is over!
Kelly, a political refugee and friend of Jack's sister is targeted for revenge by the man her father sent to prison. Armed with nothing but heroic courage and skills born from their childhood dreams, Jack and his friends fight a battle against an enemy who will stop at nothing to get what he wants. If Jack is to survive, he and his friends must work as a team and even then, winning comes at a terrible price.
