A widow fleeing greedy relatives draws an enchanted sword and releases the immortal warrior bound inside it.
The book shares a world with other Kingfisher novels but gives Halla and Sarkis a complete central arc. It is therefore treated as a standalone commitment rather than a required series entry.
Best if you want
- Adult fantasy romance with humor, practical problems, and mature leads.
- A self-contained relationship inside the wider World of the White Rat.
Think twice if you need
- Epic stakes, dense politics, or a large magic system.
- Romance kept outside the central resolution.
