The Red Prince by Timothy Snyder

Timothy Snyder's biography of Archduke Wilhelm of Austria, son of Archduke Karl Stephan, is a magnificent, well-researched study.

The book has been published in the US and in the UK.  Basic Books, the American publisher, released a trade paperback edition in September.
