Dion Shepherd Jr. uses his experience as an undercover inmate to offer insight into how to prepare for life's battle through mental fortitude and moral strength and what we can learn from warfare in our day-to-day lives.

If you think of war, you think of blood, guns, and knives. But in today's world, war is fought on a different front.

Dion Shepherd Jr M.A.S. has a bachelor's in Criminal Justice from Western Michigan University and a master's in Criminology, Law & Society from the University of California, Irvine.

Living in the modern world is like living in a warzone; you can't walk outside without facing some form of conflict.

There's no right or wrong answer for preparing for battle on a physical or spiritual level, only experiences to learn from. The world is not white or black. There will always be gray areas.

If You Want Peace, Prepare for War originates from notes Shepherd made while undercover in jail on the award-winning docuseries 60 Days In.

Shepherd examines the notion that war can be seen as a necessary evil and teaches readers how to prepare for battle while striving to maintain peace.
