4.5/5 stars 
 I absolutely devoured this book and I loved it! I read All the Bright Places earlier this year and enjoyed it a lot, but I think Holding Up the Universe made me even happier. The two main characters were a bit quirky and that's what made the story so good and feel so real. I loved Libby and all of her confidence and amazing-ness. Overall, loved this book and I can't wait to see what Jennifer Niven comes out with next!
