Oss'stera by Ross Hightower and Deb Heim is the third book in the Spirit Song: Rebels Rising epic fantasy series. In book one, Argren Blue, Alar leads Oss’stera against the Vollen Empire, questioning their efforts after repeated failures until a witch’s mission to infiltrate an Inquisition stronghold forces a confrontation with greater consequences. In book two, Desulti, after meeting a Desulti assassin, Tove leaves her tribe to train as their first Alle’oss recruit, soon discovering the group’s hidden purpose may endanger her life and the rebellion she supports. Now, Alar leads the Oss’stera rebels against the Vollen Empire’s repression of the Alle’oss. With Scilla and Ukrit, he plans to infiltrate an elite art event, steal a noble’s treasure, and escape undetected. Using his ability as a realm walker, Alar hopes to secure funding for the rebellion while avoiding capture and execution.

In Oss’stera by Ross Hightower and Deb Heim, the writing is wonderful in its point of view shifts, matching the careful construction of a world fractured by shifting alliances and ideological enforcement. I love the ties between political and cultural forces, such as the Desulti Order’s maneuvers and the Inquisition’s pursuit of Alle’oss artists, which is a brilliantly unique element that elevates institutions and belief systems as genuine forces of disruption. Art is not mere ornament but a source of disruption, with creative expression prompting accusations of treason. A single painting can trigger a raid, and this isn’t ornamental worldbuilding; it’s central to how power operates. There is romance and some surprises, and overall, Hightower and Heim deliver another solid installment that holds up under the pressure of its huge ambition, and levels up the series. Very highly recommended.

Oss'stera is the third book in the Spirit Song: Rebels Rising series by Ross Hightower and Deb Heim. The story follows Alar as he fights against the oppressive Vollen Empire. Alar is the leader of the insurgent group Oss’stera, who want to bring life back to their people. However, the Empire wants to erase the culture of the Alle’oss people. Alongside his loyal allies, Scilla and Ukrit, Alar creates a bold plan to infiltrate an elite art gala hosted by their enemy and steal a lord’s treasure to fund their revolution. But the stakes are high, and one misstep could mean death. As Alar wrestles with his unique ability as a realm walker, the team navigates a dangerous game of deception and survival against the enemy, who is far more dangerous and powerful. Can Alar and his allies make it out alive? Or is this the end of the road for them?

Authors Ross Hightower and Deb Heim created an incredible world where Alar, Scilla, and Ukrit exist under the oppression of the Vollen Empire. This epic fantasy had everything I love about this genre. The protagonist is beautifully developed, the plot is fantastic, and the character development is incredible. I loved the dynamic between the golden trio of this story. I loved their planning sessions, how they talked everything through, and how they supported each other. The world-building is layered, perfectly executed, and the authors ensure that readers are immersed in the world. Alar is a relatable character. He wears his flaws like a badge of honor and doesn’t hide them. I loved this story and cannot wait to read the previous novels in the series!
