This is a must have for anyone who's seen gravity falls! However I would NOT recommend this to anyone who hasn't seen the show or all the episodes in order cause it contains lots of spoilers and probably wouldn't make sense to someone who hasn't seen the show. I pre ordered my copy and got it the day it was released, I have since then read it too many times to count and not a single page has come loose but maybe I just got lucky and my copy was made with a better batch of glue than everyone else's. Overall, the binding problem definitely seems to have been fixed since then so if you're thinking about buying the book nowadays don't let the reviews about the bad binding stop you! I was a bit disappointed that cipher hunt page wasn't in here cause it looked like a journal page but oh well. I however was not disappointed by the lack of invisible ink since Alex said on his twitter before journal 3 was released that it wouldn't contain the invisible ink so I wasn't expecting it too. I also pre-ordered the journal 3: special edition! I hope the success of Journal 3 will lead to more gravity falls merchandise!

EDIT: Journal 3 is also a #1 New York Times bestseller and has been on the New York Times bestseller list for 34 weeks straight! And it's still on the New York Times bestseller seller list to this day!, and since it's only at #5 after 34 weeks on the list it will probably remain on the list for a long time to come! Journal 3 also was on Barnes and nobles top 100 books list at #2, and it made the top 20 customer favorite books list for kids and young adults on amazon in 2016! Also, Forget the age range too, I'm 16 (almost 17) and I love this book!

EDIT 2: Now Journal 3 has been on the NYT bestseller list for 46 weeks! Gravity Falls fans are the best!
