I picked up one of his books in Santiago...but they didn't have that particular one. Still, very good.
The weather was upper 40's in the morning and 70's during the day. I was at the tail end of 2 weeks of constant rain. Flowers in full bloom; heather, gorsh, all sorts of things! Cuckoo bird called out every morning as I walked to see the sunrise. Cafe con leche ( coffee with milk) was the best in the entire world. People had such spirit...you would walk or sleep in the albergue with them and not see them for days and then there they are, full of stories and sharing a meal.
gear-wise...if you go in the heat of the summer, just bring a travel sheet and a pillowcase. Sleeping is coed dorms and varies from 4 in a room to 50 in a room. Bring earplugs. I just had a change of shirts and undies, and a sleepshirt with running shorts. Extra socks but I never used them. You can wash your clothes at the albergue and they provide racks or a line. I brought some thin rope to string across my bed as an extra line to hang things. You can always pick up food for lunch and nibbles in the towns. I wore a nylon jacket that I waterproofed for rain gear. Get a good hat for the sun!! Lots of sunscreen. Good shoes 1/2 size larger. The downhills on the mountains is just that...straight down. I didn't use poles, but many did. I found that I didn't need them except maybe for a few times. Go light, go light, go light. Buy something called Voltaren creme which is an analgesic inflamation pain reducing non-steroid creme. Works wonders on swollen feet. 15 minutes and pain and swelling gone.
You may want to stay in a hotel from time to time just to have some personal time and cleaning time. Some albergues offer a washing machine for 3 Euros. Some have internet for 1 Euro 25 minutes. Most albergues cost 5-9 euros anight. meals were 6-9 euros. breakfast can be had at any bar after 8am. Try the liquer Orujo to help you sleep or warm you up. We hit snow and rain in the mountains, so be prepared. I had a thick undertop for that day. You don't need to carry more than a liter of water at any time. Lots of fountains for pilgrims.
You will make friends from all over the owrld, no matter where you begin. Just begin.
