The famous quote by William Shakespeare, "Love all, trust a few, do wrong to none." is a good representation of what drives the plot in Unknown Alliance.

There's a storm headed for Brookfield—it has more to do with a father's rage than it does the weather. After someone assaults a teenage girl at a neighborhood party, the victim's desperate father asks Mac MacKenna for help. There's a catch—no police.

After eight deployments to the middle east and 20 years in an elite special ops unit in the U.S. Air Force, Sergeant Mac MacKenna returned to his hometown to live a quiet life—until the police chief asked him to pose as a marshal at Brookfield Academy where crime outranks grade point averages.

Mac doesn't know the victim, and he's never met her father, but the air force trained him to aid others at all costs and keep his missions secret.
