Christchurch scientist Andrew Bagshaw was killed in Ukraine in January, while volunteering as an aid worker, helping evacuees flee the front line.
He and fellow British volunteer Christopher Parry were trying to rescue an elderly woman in an area of intense military action in the city of Soledar, when their car was hit by an artillery shell in January. Andrew was 47.
His parents, Dame Sue and Dr Phillip Bagshaw and others have paid tribute to their son in a new book released today.
The Quiet Hero is written by award-winning journalist Phillip Matthews and paints a picture of the unique man he was, and why he risked, and ultimately lost his life.
