We love the Book Drop subscription! I have purchased one for both my father and myself and it was fun to get a surprise each month - the book was always something I never would have picked out myself, but that I always enjoyed reading. My 13-year-old daughter is a voracious reader, so we purchased a yearlong subscription last year for Christmas - I wasn’t sure if she’d like it, but she is always devouring books, and I thought it would be a fun way to introduce her to new authors. She loved it so much she specifically put it on her Christmas list this year, and one of the books is part of a series she is now enjoying as well. Can’t say enough great things about this service!
