I love this book. I first read it in 1975 and I've read it several times since. Considering that it was written in 1971 and there were no internet or cell phones, it holds up really well. There are very few references that lead me to believe that it was written in 1971 and not 2017. What I like the most is that it's set in Toronto and the surrounding area. It's the first time I've read a book centred in a city that I know so I recognized all the streets/landmarks etc. I was not able to find a digital copy at Amazon or Kobo, so I purchased this hardcover on eBay.
