Overall Content Rating: Parents Strongly Cautioned PG-13

This military fantasy prequel follows cadets and soldiers through training, deployment, and a dangerous mission abroad, with a developing romance between two young adults amid political pressure and combat. Language stays relatively light in the samples, with occasional mild crude talk and some British-style harsh intensifiers in dialogue. Parents should know the plot includes physical violence, visible injuries, and threats of sale and coercion against a female character, plus discussion of rape and a situation reviewers describe as peril of a sexual nature without graphic on-page sex. There is no sampled hate speech, graphic torture, or strong profanity on every page; content fits a teen action audience rather than young children.

About this book

Sorvashti is a captive. Jet is a soldier. Both harness the primal power of aether. The war is over, but the Revoth want their land back. Kidnapping, ransom, and slavery fund their terrorism, but bombing Jet’s hometown was the final straw. Viper Unit is dispatched to take the Revoth down. But the special forces have no need for a mind-reading ‘fairy’—unless Jet can prove himself as a sniper. Sorvashti’s clan demands she take one of the seven oaths, but her father’s political status has already chosen for her—and made her a prime target for ransom. When Jet and Sorvashti meet behind enemy lines, revenge intertwines with survival… and a spark between them neither can ignore. --- This novella takes place 6 years before the storm of Sentinel.
