My Soul To Lose is a prequel novella to Rachel Vincent's popular series, Soul Screamers, which I have yet to read! While I think it probably isn't absolutely necessary to read this novella before the rest of the series, I found it to be a lovely introduction to the world and characters. It left me with a huge urge to read the first book which hopefully I'll get to do really soon! Sometimes novellas can be lacking in substance or feel like they were cut short but this one certainly wasn't.
