5. Gravity Falls: Journal 3 by Alex Hirsch


This book is best enjoyed after watching Gravity Falls, a Disney animated television series to fully understand the context. The journal was brought to life by illustrators Andy Gonsalves and Stephanie Ramirez, and was originally featured in the series. There is an amazing cast of characters and mysterious element which really appeals to all age groups.

Gravity Falls follows twin brother and sister/partners-in-crime Dipper and Mabel Pines who are sent to their Gruncle (great uncle) Stan in Gravity Falls, Oregon for the summer. Mabel sees this as an opportunity to explore and meet new friends, while Dipper thinks that this will be a boring season- that is, until he finds a strange journal in the middle of the woods.

The journal contains entries from an unknown author speaking about his experiences in the town, additional notes from Dipper and Mabel, and an epilogue ending the series with cool illustrations of monsters and the setting. This book adds some exclusive content that was never seen in the episodes. This is the type of book I wish I read when I was young. Nevertheless, I enjoyed reading the journal that deals with the mystery surrounding Gravity Falls.

Are you a gifted child looking for special opportunities?

The Mysterious Benedict Society is the first book in a popular middle grade mystery series. It is such a joy to read and discover alongside the four misfit main characters. After passing the tests, they have to go undercover at the Learning Institute for the Very Enlightened (LIVE) where the unthinkable horror is happening.

This story has a perfect balance of plot and characters. The different trials tested my wits with mind-blowing puzzles, and I couldn’t ask for more from a mystery read. The characters have distinct characteristics that are essential to the story. Political issues, friendship, and family are also explored, making this a wonderfully well-rounded read for a young audience.

2. The Newspaper Club by Beth Vrabel


The park may not be as safe as it used to be. A lot of rumors circulated around it which resulted in the park closing until further investigation. This may be an ordinary park to everyone in Bear Creek, but not to Nellie Murrow. This has been her sacred place, where she and her dad would talk frequently before he left to work. Now, it’s up to her and her potential newspaper club to find out the truth.

Reporters are brave in their pursuit of their story.

This mystery explores the importance of journalism and of taking part in the community. As young as Nellie seems to be, she embodies the characteristics of a true journalist that she probably got from her supportive parents which will surely motivate young readers today.
