Very dishonest subscription model. The titles I want to read suddenly become "Available Soon" once I hit the 4-book threshold. Apparently you throttle the number of books we can read per month which is utterly stupid. The subscription model you claim to offer is "unlimited" but in reality is very limited. 4 books read and 85% of my saved books are no longer available. This should be relayed before the user pays for the sub. Kindle Unlimited is thankfully not similarly scam-y. Unsubbed.
