Let me first start with saying I love Kristen Ashley and have been reading her books for years! 
 That's why it pains me to say this book was not good for me. I feel like I'm betraying her by saying so and my KA fan club card will be revoked after being hunted down by crazed KA super fans. 
 Despite this very rational fear;) I have to be honest when reviewing! Here are some points on what I had problems with: 
 - Merry and Cher. Cher and Merry. They together were not in my opinion captivating enough to warrant an entire book. If KA really wanted to add on to the series this could have been a short novella. 
 - The characters personalities and background/history felt so played out that I felt I was reading a lesser quality imitation of KA. Almost as though it was written by someone else who did not know how to make the story unique despite the all the books in this series being very similar in premise and 'feels' but still knew all the phrases to use 'Christ, if I didn't know you were worth it, I'd walk out the door' and so on. 
 - It could have been edited down to avoid such repetitive scenes. I actually found myself skipping/skimming sections that just kind of bored me, which leads me to my next point. 
 - I did not feel the chemistry I usual feel with the couples in the KA books. Even though the Burg series is pretty much vanilla in regards to the sex. I was still hoping to feel the sparks but nope, nothing. I got so bored during some of the sex scenes I ended up skimming through it which is NOT like me at all. 
 - As a PLUS- I did really like to read KA's new book and get back into the world she spectacularly created and read about the other characters from the series like Colt and Cal. 
 Overall I am giving Hold On 2 stars. I will not be re-reading this particular book like I do with other KA books. Sincerely hope to read some more from KA soon, maybe from her other series like Unfinished Hero, Chaos or a new series!
