I’ve signed up for a product like this before - check out Oyster. They ended up getting shut down, but I enjoyed it while I had it.

I think your biggest challenge will be at your price point, I would need to read at least two moderately expensive books in order for the product to be worth it.

I remember struggling to keep up that pace - I was ready to churn the subscription before they shut down.

Another thought is a much lower price point with less expensive books (lots of old famous books are now part of public domain). Even for a free book, I would pay a trivial monthly cost for a better reading experience. I’m thinking Amazon’s Prime Kindle reading bundle.

Hope this helps!
