Reading order advice: Read this after you read The Siren Depths. Three of the stories explicitly say they happen after that book.

I think the stories were written at that time, but this collection was published last. I wouldn't recommend reading it last (like I did). The novella really sets you up for the final two books.

I'd also recommend you read this one first after Siren, then the other short story book after it. They both should be read before you read the last two Raksura books.

Worth the read though.
