As a huge Rough Rider fan I have been a part of the group that has been not so patiently waiting for Boone and Sierra's story. They were the two characters that made Gone Country for me (Yeah, I'm a RR fan but GC was not a fav...can't love 'em all unfortunately) and the way LJ left things with Boone and Sierra was heartbreaking. So I did the happy squee thing when it was announced that a book was in the works for them and did a squee/happy dance when I got my hands on an ARC and I was not disappointed. Ms. James gave Boone and Sierra (and all Rough Rider fans) the Happily Ever After they so richly deserved. 
 It was hard to not love Boone and Sierra throughout the book. Yes, there were times when I wanted to throttle them both, but there weren't that many. Sierra is feisty, determined, ambitious and highly intelligent. She has sweet and snarky down pat and a generous heart. I loved getting to know the woman she's become and the little quirks that she has. Boone still holds himself just a little apart from everyone but after being in the military he's more solid and grounded. He's sweet, sexy as hell and once he sets his sights on something, he doesn't back down. 
 With four years of waiting for the conclusion of Sierra and Boone's story I went through quite a few scenarios in my head as to what the journey to their HEA would be like and found the one that was chosen for them to be perfect. Some will think certain things happen too fast, some too slow or that "more" should have happened, but the fact of the matter is that despite everything they were best friends and even as Sierra tries her best to keep Boone at arm's length that fact keeps popping up and is what ultimately has Sierra letting the past go and following her heart. Well, that, Boone's determination to get a second chance and the helpful pushes from their friends and the McKay-kateers. But what comes out of it all is the undeniable fact that they were meant for each other. I loved watching as they got to know each other again and finding that they loved and admired the people they'd become. They had some really sweet, really sexy and really funny moments as well as some heartbreaking ones that showed how deep their connection was and why they were always meant to be. 
 Now for those of you who've read any of my reviews were the series revolves around a family or tight knit group of friends know how much I LOVE well written supporting characters and Ms. James does not disappoint! As I stated, I am a huge RR fan and loved keeping up with all the kids ~ even though that was a huge effort considering how many there are ~ so getting to spend time with the McKay-kateers (Kyler, Anton and Hayden) and being able to get glimpses into their personalities was what kicked this book up a notch for me. Mase, Lu and Raj were also great characters and I'm hoping that we either get to spend more time with them throughout the series or that they get their own books/novellas. We do get a little McKay and West family time in the book and, without giving away anything, there are some secrets revealed that had me doing the blink, blink thing. 
 As I've already stated, I'm a huge Rough Riders (and Blacktop Cowboys) fan and from the first page of Unbreak My Heart I felt like I had come home and was surrounded by old friends. This book maybe a spin off, but that family feel of the RR series was there from the start and I can't wait to see what Ms. James has up her sleeve for the next generation!
