This one was well received during our spooky reads month in the classroom. It is second in the Merlin 🧙‍♀️ Missions. Jack and Annie are back. The Raven 🐦‍⬛ King is a scary character. We meet a young raven named ROC who needs to be rescued. A haunted castle is the setting. A lost diamond needs to be found. A mystery will be solved. Highly recommended!

This book is the second in the "Merlin Mission" series. It follows the first, with a magical trip to Camelot. Both this book and the one preceeding it diverge from her previous stories, by delving into the folklore and mythology that comes from Britain and other places, rather than actual historical events. Her stories are adventurous and exciting and we look forward to the next, but overall, I prefer her earlier stories.

I read this with a group of my 2nd graders and they LOVED it! They have been reading others in the series because of this book. There are fantastic ideas for extension activities on Osborne's website. If your child likes this book, check out the site!

Y’all, I read Magic Tree House when I was younger, but it was never a series I read all the way through. People told me to go back and give them a try, so that’s what I am doing as a filler in between my other reads. These books are not my usual reading level, but they are a good read!

This book follows Jack and Annie as they go back to All Hallows Eve to a Haunted Castle. They were given a mission by Merlin, to restore order back to the castle. You follow along as they encounter ravens, magic twigs, and invisible children! The book is well wrote and has some cool drawings of the story throughout. I don’t have anything bad to say about it! It was a good, quick read. Worth a try!

Such a fun read-aloud with my son. He is all about "spooky" things, so this was right up his alley. I loved the setting of an old castle and the fantasy elements were a lot of fun. This series never disappoints.

Not the best MTH I've read, but an interesting take on old legends and folklore. I would've like more Halloween based on the title, but The Raven King and Merlin both make appearances.

Another solid adventure for elementary school readers and middle school readers. My son loves it and I enjoy reading along with him.

I decided a few months ago that I wanted to start reading 1-2 children’s books a year, and this is one that I remember being one of my favorites when I was a kid. It feels kinda weird to rate it as an adult, but ultimately, I love how inspiring it is. Jack and Annie overcome instances of adversity during their journey and they work together as a team. It’s a mystery and a fantasy wrapped into one, and if I’m being honest, it had more suspense that some adult mystery novels that I’ve read! It’s very cute and heartwarming, the illustrations are fantastic, and I can absolutely understand why I loved it so much as a kid.

The second of the Merlin Missions, taking place amid mythology rather than real events, for the most part at least. As usual, lovely illustrations. These are slightly longer than the original series, making them an easy step up as kids advance in reading comprehension and skill. There is no fact tracker to this one.

This was another great tale in a great series. I love the author's notes at the end, explaining where Osborne got her inspiration from. The Raven King was definitely an interesting character, and I like that Teddy (as well as Merlin) is becoming a more developed character in the stories. I highly recommend this book and this children's series.

This book is amazing. I love how this adventure goes. While I was reading this book it felt like i was there too. At first I thought something bad was going to happen when they got to the castle then i realized that nothing bad happened.

This was a quick, cute story about how two kids helped save a whole kingdom by helping out one family. The family was supposed to be guarding a Stine, but the Raven King stole it anyway. The kids' mission was to find out who had the stone and to get it back.

I liked when Jack and Annie defeated the Raven King. I gave it a four because it was a little creepy.

My 7 year old says, “just spooky enough to get into the Halloween spirit, but not too scary so you don’t get bad dreams. I love the Merlin mysteries because I love Camelot and want to find Excalibur when I grow up.”
