Just as much fun as the previous installments. Although I am conflicted about the ending. The Raven is a very intriguing addition, however, I am also a bit sad about the series no longer consisting of stand alone books, since cliffhangers suck. I also really like that this series doesn't shy away from consequences given how dark the plots can get. It's definitely still a children's series, but people really die and it seems like Sally may be permanently disabled (which will also be really important representation). Children understand when they're being condescended to and I like that this series doesn't do that.

First reread: Jan 2023
I am screaming (seems my reaction to finishing this didn't change) I forgot how incredible this book is. It is perfect, it is incredible, it is stunning. It is the moment. Tomorrow I will start book 4 and then read book 5 and then BOOK SIX IS HERE I AM SO EXCITED.

First read: July 2021
I'm not even sure why I'm writing this because I have no thoughts other than a ceaseless scream. I can't breathe. This was so good?? I love the relationship Tom and Christopher have. I love Sally. She's a queen. She's so smart and badass. I love Christopher. I relate to Tom's love of food. Did I mention I really love Tom and Christopher's relationship? It makes me incredibly happy. Another reason I loved this one so much is because the characters are searching for the templar treasure, which is the same thing being searched for in National Treasure. And (don't judge me) that is one of my favorite movies of all time. Anyway. I loved this one. The climax was just *chefs kiss*. Like wow. Obsessed. I'm also super excited for the next one. The letter at the end gave me chills and the blurb for book 4 is ahhhHHH. The memory loss thing better be good though. We know how that went down in The Deceiver's Heart. We'll see.

It was okay. It wasn't a bad book (but it also wasn't the best espionage/coding/mystery book I've read). I would have really loved it, had I read it, say, two years ago. The cover says it's for ages 10-14, and i'm currently 14 and I feel like I was a tiny bit too old to enjoy it. It was really fun to solve the codes alongside Christopher Rowe. Fun Fact: I accidentally borrowed the 3rd book instead of the 1st book, so now I'm reading the 2nd book then onto the 1st. That wasn't funny :)

4.5

I share tom’s views on the French

This was excellent. I particularly enjoyed the visit to Paris and how it evoked Louis XIV's reign. Highly recommend this series if you like historical mysteries.

This is a great mid-grade/YA novel series and one of my son's favourites. It has an excellent combination of adventure, mystery and great historical information. Somehow the age of the protagonist doesn't slow him down. This story will appeal to multiple audience and is a great read.

I absolutely love this series!!! The characters, the setting, the plots... everything is so GOOD. I love the way it keeps you guessing until the very end... (especially in this instalment). The way fiction is interwoven so flawlessly with history is so interesting, you learn so much and you don't even realize it. I can't wait for the next one.
