Since this book has not yet been released, I'm going to try to keep this review as spoiler free as possible. 
 I'll be honest and say that I didn't really pay all that much attention to Zeb and Sayer when these characters were introduced in the Marked Men series, so I started Built with no preconceived notions of how I would feel about these characters. 
 Zeb and Sayer come from two very different backgrounds. Sayer comes from money. She's a lawyer, and she's a master at hiding her emotions. Zeb comes from a different background, and he's got some trouble with the law that will follow him around for the rest of his life. But the physical attraction between these two characters is off the charts, and there's no way they are going to stay away from each other. I fell for Sayer right away when she makes it clear that Zeb's history isn't a deal-breaker for them--underneath her prim and proper exterior is a woman with a huge heart and I loved that about her. I got her. 
 It takes a while for these two to connect physically, and when they do, there's no going back for Zeb. They both scratch each other's itch in a significant way, and they scorch up the pages when they come together. There's more than just sex between them too, but it's Sayer's past history that could keep her from the happiness she finds when she's with Zeb. 
 When Zeb gets some shocking news, he needs Sayer's professional help and she's his biggest advocate. Her big heart won't let anything get in the way of Zeb getting what he wants in his life. This wrecks havoc with their relationship in a major way, forcing Zeb to make a difficult decision of his own that could end the wonderful relationship between these two unlikely lovers. 
 I loved both Zeb and Sayer in a way that left me surprised and happy. Jay Crownover does a great job (as usual) presenting the reader with two very interesting characters. There's excellent and subtle commentary about how hateful words and behaviors can be as devastating as fists and fighting. And Zeb is an incredible hero in this -- his maturity and ability to get to the heart of things just made me fall for him the same way I fell for my favorite Marked Men. He's got some great lines that just ripped my heart out and I loved that. 
 Built is a great start to this aptly named Saints of Denver series. I loved everything about it -- the characters, the story, and the little bits of the Marked Men that are sprinkled throughout the book and help anchor it to this Denver world Jay Crownover has created. Recommended.
