So pleasantly surprised by this set!  By the picture I thought this was a connected stack... possibly wood... that looked like books.  They are actually real books!  (Same content for each book) I split mine and I love the effect.  I just ordered some high end coffee table books as well, but these were perfect for my espresso shelves.  I’m a huge fan of all 4 women and the books are on trend with flowers.  Perfect addition to glam up your space.  Highly recommend!!!
