Parents' Guide to Oathbound: The Legendborn Cycle, Book 3

Deonn masterfully expands the supernatural lore in this riveting yet character-driven middle installment, focusing on Bree's journey toward harnessing her powers. The novel revisits key events and details from the previous books—helpful for readers who may not recall everything, like the hierarchy of demons, supernatural abilities, and aether colors—though it does result in some exposition-heavy passages. New characters abound, but the most compelling additions are Zoe and Elijah, twin demon wards of the Shadow King. Readers will be particularly drawn to Zoe's evolving friendship with Bree, which begins as tense and adversarial but deepens into something powerful and empathetic.

A major plot thread involves Bree losing a significant portion of her memories, leaving her with only overwhelming emotions—shame, guilt, longing, regret—tied to unrecognizable figures from her past. As she reunites with key characters, she must piece together her past while forging new dynamics. Another driving force is her reluctant bond to the Shadow King due to an ancestral oath, which binds her to fulfill an obligation until she can find a way to break free. Romance-wise, if Bloodmarked was Sel's book, Oathbound belongs to Nick. Unlike most love triangles where the rivals remain distant or antagonistic, the Legendborn Cycle echoes Cassandra Clare's Infernal Devices trilogy, where the two love interests share an intimate, soul-deep bond. This emotional entanglement complicates matters further, but this book solidifies the relationship that began in Legendborn. A lot unfolds in Oathbound, with shocking twists that raise the stakes for the fourth and fifth books, setting the stage for an even more intense battle ahead.
