I am very impressed with introverts retreats box subscription. I gifted it to my mother-in-law who has a big reader and although I did have an issue with the genre of book that was delivered to my mother-in-law this was fixed immediately and three new books were sent. I was in thriller as the genre because my mother-in-law likes to read mystery novels however the book she received or supernatural and fantasy in nature. It’s true that categories can be misunderstood and genres have a wide range of interpretation but what impresses me most about this box company is their customer service! Fantastic!
