The Andrew Skurka book will be released on Feb 21.
I have a pre-release copy and I LOVE it! Lots of energy in the writing and I learned more than I thought I would - So even if you are an old hand at UL it still has plenty for you - especially inspiration!
It will be available many places later this month, including the MLD site.
I HIGHLY ENCOURAGE you to buy it directly from his site, andrewskurka.com, since he will get the sale and you will get a signed copy- SO surf over there to pre-order.
More info on the book at his website.
