Honestly speaking, this book was a vast improvement from the previous one, even if it was a bit irritating at times.
Golden Gate follows the City Spies after the events of the first book, this time telling the story from Sydney's perspective. Sydney and Brooklyn have been sent on an undercover mission on a marine research vessel, and things don't exactly as planned. To add to the situation, new intel comes in regarding the death of an agent in San Francisco who was looking into Magpie - a double agent in the agency. Once again, it's up to the City Spies to save the day.
My biggest problem with the last book was how seemingly perfect Brooklyn was at everything that she tried in regards to espionage, even more so than the other spies. I'm glad that this was addressed, even if a lot of drama came out of it. In a way, what happened was expected, but it was still,,, weird to read.
The plot, thankfully, is better and more substantial than the first book as well. There are actually quite a few plotlines being discussed as well as playing out this time, which made for a more interesting read.
Even so, the identity of the double agent was pretty easy to figure out. This time, however, I liked that there were clues regarding the true identity of Magpie, and everything sort of built up to the big reveal, rather than everything being out in the open since the very beginning.
There were more backstory reveals in this book, which I really liked, especially those of the City Spies that hadn't been given as much of the spotlight in the previous book. Again, same as the last book as well, I liked the friendships between the City Spies and how they grew in this book as well.
This book felt pretty short, but probably only because I didn't force myself to read it as much as the first one, which made for a short yet action-packed reading experience. It was definitely more enjoyable than the first book, to say the least. (Could this have something to do with the fact that it wasn't all about how pErFeCt Brooklyn was? Perhaps.)
Overall, this book was a vast improvement from the previous one. Even if the beginning was a bit weird, I liked how different plotlines that had only been touched upon in the previous book really began to come into play with this book, as well as how the character dynamics were clearer in this book. That, of course, isn't to mention all of the action that just felt more fun and characteristic of a middle-grade adventure novel that was included in this novel.
