What is the best or most interesting soaring book you have read?

I will be choosing a new one out of these, so any recommendations?

On Quite Wings
The Art and Technique of Soaring
Cross-Country Soaring
The Joy of Soaring
Soaring Valley
America's Soaring Book
Soaring Cross Country
With Wings as Eagles
The Powerless Ones
The Soaring Pilot
Once Upon a Thermal
Glider Flying
Gliding A Handbook on Soaring Flight
New Soaring Pilot
On Being a Bird
Soar America
Winning
Advanced Soaring
Soar Sierra

Your list is missing all of Gren Siebel's books, which IMO are some of the best soaring books I've read.

Gaggle of One
Pilot's Choice
After All
