The Obsidian Tower, by Melissa Caruso, is the first in a new spinoff series set in the Tethered Mage world. Normally, I am not one for spinoff series; I enjoy jumping into new worlds rather than returning to ones I know for what is often a B-list version of the original series I liked. However, in Caruso’s instance, I made an exception as she continued to expand the scope of her world and story from the original series and left a lot of room for exploration. In addition, her writing quality has improved with each book she has put out, and I was curious to see if this trend continued. So I decided to dig into The Obsidian Tower, and am happy to say it is a delightful book filled with delicious mysteries.
If you are new to Melissa Caruso’s work I recommend you start with her first book The Tethered Mage (reviewed here). But, if you just can’t wait to read The Obsidian Tower, it is a completely standalone series set sometime after Caruso’s initial series. Caruso’s world is one of rampant dangerous magic and antagonistic empires that love political cloak and dagger shenanigans. The protagonist of Obsidian is Ryx, a royal mage whose job is to guard the aforementioned obsidian tower that has been in her family for generations. No one knows what is inside it or what it does, but the family lore is quite clear on what her duties are – don’t let it be opened. Unsurprisingly, Ryx fails at this duty almost immediately at the start of the book, and the tower is breached. But what Ryx finds inside is confusing and puzzling, and sets off an exciting investigation as to what the purpose of the tower was and why was it sealed.
Caruso’s original series was primarily a political drama, with some romance splashed in on the side. The Obsidian Tower is a mystery book first, with a large side of political drama. I really enjoy this genre change-up and actually think that Caruso is a stronger mystery writer than she is a romance writer. The tower is a fun enigma, and I was very much invested in pulling apart its secrets. Caruso is very skillful in how she parcels out information, and the pacing of the book is excellent, constantly sitting at a low burn.
In addition, Ryx is an excellent protagonist who brings a lot to the table. For starters, she is a viviomancer – a magic-user whose power is directly entwined with the land her family controls. It is a unique and interesting magic that was used primarily by the antagonists in Caruso’s first series, and it is definitely fun seeing it used from the POV of the characters you are rooting for in Obsidian. Ryx has the added complication of her magic being “broken.” She had an accident while growing up, and it caused her magic to somehow go wrong. Now she is a magical Midas, siphoning the life energy out of anything near her and killing literally everything she touches. Caruso did a lot more with this premise than I was expecting, and it was one of my favorite parts of the story. Ryx essentially has to live like a combination of a cripple and leper – using specialized tools that she can’t break with her power and never coming near another human for fear of killing them. There is a nice exploration of what this does to her emotionally and I really enjoyed hearing a story from someone in this POV. A+ protagonist, sign me up for more.
However, I was less impressed with the supporting cast in Obsidian, especially compared to Caruso’s first series. The side characters consist of primarily three groups: 1) Ryx’s family members and servants, 2) envoys and ambassadors from various other political powers who are in her home for a summit, and 3) an independent group of mages from different countries who investigate magical disasters like a fantasy United Nations. There were a few interesting individuals from each of the three groups, but I found most of the supporting cast forgettable and wish they had more depth (like the large support cast in Caruso’s first series did). On the other hand, the worldbuilding and prose continue to improve with every book Caruso writes. Obsidian benefits massively from the groundwork that the previous series laid, but does a fantastic job expanding the maps and magic of the world. The prose is slightly better and I am constantly impressed by Caruso’s drive to improve and streamline her writing.
Overall, The Obsidian Tower is a great spinoff and fun for new and old fans of Caruso’s writing. The book is packed with fun mysteries and a highly original protagonist with a unique POV. The pacing and prose are good and I found almost nothing to complain about. The Quill to Live gives a warm recommendation that you check out The Obsidian Tower, and also Caruso’s previous books if you haven’t had a chance to read them yet.
Rating: The Obsidian Tower – 8.5/10
