Gideon Nav is an orphan and has been raised in the Ninth House since she can remember. She is going to once again try to escape from this planet and enlist in the army. That way, she would finally be free. That plan hits a wall when 17-year-old necromancer and heir to House Nine, Harrowhank, challenges her to a fight. Gideon can run away but when Harrow offers Gideon her freedom if she wins, she chooses to fight.
Harrowhank needs a cavalier to fight for her and Gideon is the best and only hope. All nine houses have been summoned to a planet that is ruled by the First House. The Emperor has summoned all the families and the ones who solve the mystery will become immortal. Nobody knows how to become a Lyctor and can’t leave the planet until the task is completed.
Gideon and Harrow don’t get along under normal circumstances. Now, they have to work together if they want to stay alive because people start dying. Is there a monster residing in the house or is someone killing the competition?
Reading a science fantasy for the first time was a fun experience. The world building in Gideon the Ninth was complex and detailed. It has a lot of stuff going on and I like that we are shown some of House Nine and House One. That leaves a lot of stuff for Tamsyn to write about in her upcoming novels.
I really liked this book and have to admit I finished it in 2 days. What I loved was the plot, the wonderful characters, the necromancers, and the sense of humor. You will be laughing a lot and the jokes and writing land well. I definitely recommend this book to fantasy lovers, science fiction fans, and people who love a good mystery.
