Thank you NetGalley and Forever (Grand Central Publishing) for providing an ARC in exchange for an honest review. 
 Griffin Hancock is an interesting side character in the first three books of the Thoughtless series. This cocky and confident bassist of the D-Bags never fails to make me laugh on all his banters. It's nice to see that through Untamed, we get to hear his story. 
 The D-Bags becomes successful in the music industry. Being a member of a rock band, Griffin enjoys the luxury of it. He's financially stable and he can buy whatever he wants and provide the needs of his wife, Anna and daughter, Gibson. If you come to think, he's very lucky but it's not enough for him. His dream is to become a rock star and wants his chance to be on the spotlight that Kellan Kyle has but his co-band members won't allow him. He was fed up with it and decided to take another opportunity that might recognize him as a star. Kellan, Evan and Matt tried to convince him it's not a good idea but Griffin is too stubborn and eventually leaves the band. It's indeed a risky move. 
 Almost throughout the book, Griffin frustrated the hell out of me. He became a selfish, arrogant and prideful. He just threw away every opportunity he has. It greatly affected his relationship with his best friends and as well as his family. What gets me more on my nerves, he keeps on lying. I'm so close on losing my patience because of it and at the same time, I feel sad for him on being left out. Of course, there is always a consequence on all his actions. I pity him for suffering it but he have to learn his lessons and take his downfall. 
 I think I get why his co-band members / best friends didn't gave him a chance. He had the talent, and confidence but he never takes his passion seriously. If you want a spotlight, you've got to earn it. On the last seven chapters of the book (including the epilogue), there is so much character development on it. This new Griffin is more serious, responsible and down to earth at its best. Call me sappy and all, to be honest I teared up a little for him. All my frustrations are paid off and he earned everyone's respect. I admire him for that. My favorite chapters are: Chapter 23 & Chapter 25. I can't tell you why because it will be a spoiler. As always, Griffin and Anna have raging hormones. So, expect a lot of intimate scenes. They are still amusing. 
 Overall, it's a great, touching story. In the end, I must say Griffin Hancock rocked it! 
 P.S. 
 It's really nice to see Kellan Kyle again. Also, Matt and Evan <3 ;)
