I subscribed to the 3 months subscription. There is nothing interesting about the books. It was mostly undiscovered books. It wasn't even gems. I didn't enjoyed any of the books. I unsubscribed after the first month. After my 3 months ended, they charged me again. I emailed them and never received a reply. It turned out that my subscription wasn't cancelled properly, so I cancelled again. I asked for a refund, because why pay $50 for useless and uninteresting books. Customer services was very rude and hostile. I absolutely do NOT recommend this subscription. It is not worth it.
