Dolphin Song discussion

Hi all. I'm trying to set up a Giveaway. As some may know, the Giveaway set-up form asks me to enter the ASIN. I did: B099QRTH62. Which is valid, or so says Amazon KDP. The Goodreads setup comes back saying: We can't find this book. Try again.

Too, I'm not sure who to contact at Goodreads for help

I don't have much hair but this is driving me to distraction. Any help would be TRULY APPRECIATED! Yours in frustration - Tom
