3.5 stars. Good Boy is sweet and cute, although a little on the fast side. I don't think it went as deep as either Him or Us, both in plot and character development. The first half of the book was kind of a bear to get through mostly because I couldn't stand how Blake talked (calling Jess "J-Babe" REALLY bothered me, and some of his abbreviations were particularly obnoxious) or how pushy he was with Jess. It's one thing for a guy to really want a girl and be willing to show her how much he cares, but Blake toys with the line of being too much, not being able to take a hint/a straight up no, and that's disrespectful. I definitely empathized with Jess. I completely understand being in your mid-twenties and feeling directionless, changing your mind about your future, and feeling bad for relying on your family for help. The second half of the book is much better. It was sweet and fun to watch Jess and Blake learn how to be together, and I like that there wasn't a big stupid misunderstanding for the sake of a plot device. 
 I do want to say this book brought out a lot of emotions. Good Boy displayed Sarina and Elle's classic sense of humor. Their characters are funny, but their writing style is perfect to keep a light, humorous tone. And it was great to see Jamie and Wes settled and happy, especially after how emotional and difficult Us was. I absolutely shed a tear or twenty during their wedding. 
 I would recommend Good Boy to Sarina and Elle's already established fans, but I do think Him and their individual hockey series (Off Campus for Elle and Ivy Years for Sarina) are stronger works so I would encourage new readers to start with those.

 Who's a good boy? Jamie and Wes and Blake and heck, all of Elle & Sarina's readers too, regardless of gender. So excited for this!!!

 I'm glad this isn't Wes and Jamie's book because Us nearly broke me. I love that Sarina and Elle are listening to readers and exploring more in this world. After Blake, I could totally go for more books featuring more of Wes's teammates or Jamie's brothers or...
