I've really been enjoying the Ten Tiny Breaths series, and Four Seconds To Lose is a great addition to the series. I don't love it the way I loved Ten Tiny Breaths or One Tiny Lie, but I still really liked it! 
 This book focuses on Cain, who owns the strip club that Kacey works at. We don't see a lot of Kacey or Livie in this one- though they do make an appearance- but I also liked seeing Cain's story. Mostly because he's such a mystery, and I did want to know more of his story because of that. You really do find out why he does what he does, and how great of a boss he really is. 
 It fits in so well with the series, even though it has a very different vibe to it. I think I got so used to Livie and Kacey and their story that something focusing on a completely different character was going to be different. And Four Seconds To Lose is different in a good way. I just don't think I connected to it the way I felt connected to Livie and Kacey. 
 We do see quite a bit of Dan and Storm in this one, and I wish they got their own book. I know that we get quite a bit of their story throughout the series, but there's a part of me that wants them to have their own book! And I'd love to see a book about Nate, who also makes quite a few appearances throughout the book. I did like his friendship with Cain, and it's clear they have each other's back. 
 There is a certain darkness in Four Seconds To Lose than we see in the previous 2 books, and it's definitely because Charlie and Cain have been through a lot. They both have a lot of baggage, and I don't blame them for acting the way they do. I did feel for them, and I wanted them to be happy because they deserved it so much! I also loved them together, and how Cain realized that he can't let Charlie go. 
 Let's Rate It: While I really liked Four Seconds to Lose, it also didn't have the same appeal the other books in the series have had. I like that each book in the series stands on its own, and that you don't need to read them in order...but I also love that there is a common thread that connects the books. Four Seconds To Lose gets 4 stars.
