This was such a easy, fast-paced, adventurous, fun mystery read.
The book is full of lively characters (nerds ahoy!) as well as adults who play a good role in the book (which is rare to find in most middle grade and young adult books!) alongwith a good plot involving Nicola Tesla! How crazy is that?!
Nah, that's not even the whole plot. The story is set in a school environment. One of the teacher gets threatened and vanished all of a sudden in the school premises. And the book is all about solving

Hello Again!

Lately, things have been so chaotic and I just feel like I have not been getting a ton of reading time in but then I look at my Goodreads currently-reading shelf and see that the exact opposite is happening! I am reading and reading a lot lately. I am averaging at least two books and two graphic novels a week if not more. Which is super awesome considering I am still working full time and doing everything else I need to do in my life (like house stuff, school stuff, etc...). Also, I

I received an eARC of this through NetGalley in exchange for an honest review.

Witty, fun and jam packed with mystery.

This is a great MG book for those who are wanting to get into reading the mystery genre. It has intrigue, endearing characters and an underlying historical story that really cements it in the real world.

I liked the loyal friendship aspect that really shone through the entire story from start to finish.

A BIG Thank You to Netgalley and Capstone Editions for providing me with an advanced reader’s copy of “The Secret Notebook” for my review.

I loved reading this book! I love reading about science, technology and history, and loved how the author included it in the plot.

Riley Green doesn’t feel like she fits in at her school. Her mom works for a politician, whereas the rest of the kids have politicians for parents.

A STEM mystery is afoot.

Riley lives in DC and attends a school with the kids of political high rollers. She feels like an outsider because her mom "only" works for a senator.

One day, she arrives early to chat with her teacher and finds the teacher's room ransacked and a ominous threat scrawled on the board. Then, her teacher mysteriously disappears.

Riley Green is a Nikola Tesla fanatic. She really also likes inventions and mysteries. One day, her teacher experiences a vandalism and Riley is ready to solve the mystery. She, however, finds a notebook in her backpack that seemingly belonged to Nikola Tesla. Could that be why someone vandalized her teacher’s classroom?

While I received a copy of this book for review, all opinions remain my own.

This is perfect for middle school aged girls (I would think the younger side). It is strong on the bonds of friendship and importance of being able to rely on your friends. There are some situations that are high tension but resolve quickly. I wouldn't have a problem letting my children read this (youngest is 11).

I thought Riley was a mostly likable kid. She is a smart kid in a place where she doesn't really feel like

This book is one of my favorites, mainly the way of writing, being English my second language I found it very easy to read, if there were difficult words but not so complicated that they did not make me understand the plot.
A beautiful story, with very friendly characters and who make you love them from the beginning. It is an entertaining, adorable story that you will definitely love when you read the book. It is a book that deserves a chance, if you want to venture into the English language thi

now you know what it is about, let me tell you it is a 4 star read for me. It might be my age or something, but for me, it didn't blow me away enough for a 5 star read. It is very fun to read, and I really enjoyed it. it really helped me out of a reading slump because of that. I think I read it within 2 or 3 hours.

I enjoyed the story but something was missing. If this is the first book from this author I can't wait to read the next one. The story seemed to check all the boxes a historical mystery has but I don't think there were enough breadcrumbs along the way. The decision to highlight an inventor children don't usually hear about helped this book stand out. Overall The Secret Notebook was okay just not great. ...more
