Back in 1972, I picked up a copy of this book in Pearl's Swap Shop in Seminole, Oklahoma. You could get paperback books for a dime there. The 95¢ sticker price was too much for me at the time. But I was glad I got this one. I was 14 years old and had just discovered Edgar Rice Burroughs's John Carter of Mars books (as well as Carson Napier of Venus and David Innes of Pellucidar).
I'd read Lin Carter before in the Conan books he was doing with L. Spraggue de Camp for Lancer Books and was enjoying those when I could get my hands on them. Those Conan novels were hard to acquire because the publishers were struggling, and because I was hunting for 10¢ books everyone at the time was hunting.
I was glad to get this book, but I was frustrated trying to track down the next one in the series because this one ended on a cliffhanger.
