A REAL COMMANDER-IN-CHIEF:

They are the work of an amateur painter who is focused on his craft. In the introduction, Bush writes: "I'm not sure how the art in this volume will hold up to critical eyes. After all, I'm a novice. What I am sure of is that each painting was done with a lot of care and respect."

He also cites some major 20th-century figures as personal exemplars: Lucian Freud, Wayne Thiebaud, Jamie Wyeth, Ray Turner, Fairfield Porter and Joaquín Sorolla. In the use of heavy impasto, the reduction of the face to a rough topography of color, and the particular love of sharp and sometime jarring contrasts, the work of Turner is perhaps the closest fit for comparison. But you can see what he has taken from Freud, Thiebaud and (the sadly neglected) Porter as well. The presence of Sorolla (a Spanish artist who died in 1923) suggests that underneath Bush's modernist expressionism is an unrealized hankering after old-fashioned Impressionist nuance.

Bush's opening essay and the capsule biographies he writes about each subject are charming. He lightly ribs his mother in this account of his first experience with the paint brush: "For the first time in my sixty-six years, I picked up a paintbrush that wasn't meant for drywall. I selected a tube of white paint and another labeled Burnt Umber. While I wasn't aware at the time that it was a color, I liked the name, which reminded me of Mother's cooking."

In his descriptions of the men and women he paints, he cites their struggles with grievous war wounds, post-traumatic stress disorder, traumatic brain injury and the myriad difficulties of reintegrating into civilian life. Although there is increasing concern in the medical community about whether we are over-diagnosing PTSD and including too many disparate psychological issues under its label, there is genuine empathy in Bush's embrace of the stories told by these soldiers.

Those who bristled at the former president's displays of machismo while in office (his infamous landing on an aircraft carrier and premature declaration of victory in Iraq, or his 2003 invitation to Iraqi militants to "bring 'em on") may be surprised by the fluency of his embrace of the importance of therapy, talking things through, turning to others for help, confronting pain and finding meaning. Describing Cpl. David Smith's recovery from a suicide attempt, Bush writes: "Dave sought professional counseling and got prescription medication for his anxiety, depression, and nightmares. Having confronted his trauma and learned to understand and accept it, he began building a new life."

About the PTSD of Petty Officer 3rd Class Chris Goehner, Bush writes: "Little by little, Chris started to recover. He got down from twelve medications to zero. He realized alcohol didn't numb the memories but exacerbated them. He started to participate in marathons and triathlons as therapy." A recurring narrative of hitting bottom, reaching out, then rebirth and the embrace of things like sport, travel or helping others echoes Bush's Christian understanding of redemption.
