Def concerning - just saw Red Rising expires soon (free title). Overall though Audible is such a powerful tool. In the last 7 years, I've listened to 165 books.
For important/controversial books I also buy a paper copy for just in case.
If looking for other Audible listens checkout Mysteries of the Bitcoin Citadel - free on audible (under podcasts)
