I’m in that zone myself. Last read through I had to scrounge paper copies. Your post inspired me to see if they’re on Kindle, where I do almost all my reading. I was delighted to see that they are! I splurged: https://www.amazon.com/The-Chronicles-of-Amber-10-book-series/dp/B075V7ZVKR

Book 10 Prince of Chaos is out too now: https://www.amazon.com/dp/B086ZPQ5QY

All 10 books are now on US Amazon Kindle store: https://www.amazon.com/dp/B075V7ZVKR

8 are out on the US store: https://smile.amazon.com/dp/B075V7ZVKR?ref_=dbs_s_ks_series_rwt

I'm hoping the 2 remaining books will come out soon!
