What I read: Fantasy Book Releases March 2021

The Stolen Kingdom by Jillian Boehme

the stolen kingdom book cover new fantasy book releases march 2021

Genre: YA Fantasy Romance
Pubdate: 2nd of March
Publisher: Tor Teen

The kingdom of Perin Faye was once prosperous until the throne was taken by the greedy and power-hungry Thungrave kings. The Thungrave leaders have access to dark and powerful magic, making them a force to be reckoned with. Alac Thungrave, the second son, has always been grateful that he’s not in line for the throne. He doesn’t want anything to do with the dark, stolen magic. But things might change when Maralyth Graylaern, a vintner’s daughter, discovers that her magical power is proof that she’s part of the ancient bloodline and has a claim to the throne. She gets embroiled in a plot to murder the royal family and seize the throne, but can she go through with that when she actually meets Alac, and the Thungraves don’t seem so evil after all?

I thoroughly enjoyed the Stolen Kingdom; it took a bit to get into, but the pace is really fast, and things get kicked up a notch fairly quickly. About halfway, I couldn’t seem to stop reading, and I finished the book in only a few days. The only thing I found somewhat annoying was that Perin Faye’s history was repeated a bit too much, even when it was already clear to the reader. But the growing connection between Alac and Maralyth was well-written; tension just keeps growing, especially with the murder-plot looming in the background. Moral dilemmas and difficult choices are present for both of the characters, and Jilian Boehme doesn’t shy away from writing them.

A great book to read if you love conspiracies, royal courts, and a complicated romance between enemies.

Spellmaker (Spellbreaker duology #2) by Charlie N. Holmberg

fantasy book releases march 2021 spellmaker bookcover

Genre: NA Historical Urban Fantasy Romance
Pubdate: 9th of March
Publisher: 47North

Spellmaker picks up where Spellbreaker left off: Elsie Camden knows who is behind the murders of the spellmakers and the thefts of their opuses. She just can’t do anything about it or risk being exposed as an unregistered spellbreaker. But when she refuses to join forces with the assassin, her secrets get out anyway, and Elsie is thrown in jail. Bacchus Kelsey is willing to do whatever it takes to get Elsie out of jail. He succeeds, helping Elsie become registered, but there’s one caveat: they need to get married to prove the story Bacchus made up. Between faking her lessons and questioning Bacchus’s true feelings for her, Elsie still plans to bring down the assassin who put her in jail. She needs to thwart the plans of the criminal. But she needs to be careful, or she might play right into the assassin’s hands.

In my opinion, Spellmaker was even better than Spellbreaker. There’s a lot more tension, especially with Elsie getting thrown in jail right at the beginning. I also enjoyed the growing bond between Elsie and Bacchus. A lot happens in the story, and it’s certainly never boring. All the while, you’re wondering how they’re going to stop the criminal, will they all make it out alive, and are they putting trust in the right people?

The spellbreaker duology is definitely worth a read if you enjoy a good murder mystery, an original magic system, and a slow-developing, blooming romance.
