Simply unputdownable
Format: Kindle
B N William’s field guide is fascinating. The book uncovers the bizarre reality beneath the polished propaganda of the Second World War, exploring the wonderfully weird truths where the line between brilliant innovation and sheer insanity vanishes completely. Every unusual piece of information has been verified using official declassified archives. I loved the story of Wojtek, a Syrian brown bear, who became a beloved and legendary figure, known for his unique story as an enlisted soldier. Read many more such stories and episodes in this book. You will enjoy them thoroughly.

Wonderful reading
Format: Paperback
It is a pleasure to “listen” to MLK Jr, and his description of the Montgomery boycott, mostly after reading the newest biography King, a life. Both books are highly recommended.

What a man
Format: Kindle
This book should be required reading for all Americans. MLK Jr. describes his journey through leading the bus boycotts following Rosa Parks refusal to give up her seat. MLK's conviction in nonviolent resistance even when facing the most vicious hate and attacks is extremely inspiring and admirable.
