I made a quick trip into the University Bookstore today and in the New Zealand section found a book called "Scottie" which looks like it was printed in 2008 (forgot to check for earlier publications) by a New Zealand publishing company. I also forgot to write down the name of the author (I feel like Herman may be the last name?). But it's about a New Zealand runner. I haven't been able to find it online anywhere. It's $25 NZ which is about $18 US.
Let me know if you've heard of it, already own it, want it, don't want it, etc.
I also went into one used book store where I asked the guy about running books and he looked but couldn't find any, and another where I got distracted by my friend and her visiting parents. But it's only a few blocks from my flat so I can definitely go back.
