I love this series and this author's other work, so I was confident I was going to like Interborough and I was not disappointed. Actually, I really loved this realistic story of what happens after the HEA and it's probably my favorite so far in the Five Boroughs series. 
 Raymond and David are still together, going about their lives and while the sparks still fly between them, you might say that the "honeymoon" is over in the sense that real life is presenting many challenges to the couple. The day-to-day grind is putting stress on their relationship in a major way. Raymond is working 2 jobs and going to school, and David is totally stressing out over the lack of quality time they have to spend together causing him to face many of his insecurities. When they do find time together, their conversations quickly degrade to argument because David knows something is wrong, he just can't fix it himself. If you've ever been in a relationship you can probably relate to this situation -- nothing seems to resolve their friction and even though their attraction to each other is still strong, sex is not solving their communication issues. 
 Even though it was sometimes painful, I loved the portrayal of both David and his insecurities, and Raymond and his sharp focus on work and getting ahead causing friction between them. This book presents the ebb and flow of a relationship with such realism, I loved it. Both play out their relationship frustrations in different ways that I found so familiar and could relate to. It all kept me turning the pages to see if Raymond and David could get past it all and to a better place. 
 When a serious situation at Raymond's family home brings many of the stressors to a head, both Raymond and David are faced with some serious decisions, one of them being about whether their relationship can survive long term. I'll admit to leaking a little during this part of the book, because the pain they are both feeling jumps off the page and draws you right in so that I couldn't help but hold my breath a little bit as I kept reading to find out whether they would be able to make it past this first big hurdle in their relationship. 
 This is definitely a relationship story -- and it shines a spotlight on the compromises and communication that keeps that relationship going, even when it looks like everything is very bleak. 
 Michael and Nunzio also make an important appearance in this book, as do the Qfindr principles, Oli and Caleb. 
 The epilogue is just perfect in so many ways, and I really don't want to spoil it for you so I'm not going to say much more than that. If you like romance stories that really take a hard look at what it really means to be in a relationship, I think you will love Interborough as much as I did. 
 Five big beautiful stars for David, Raymond and Santino Hassell.
