While these novellas can be purchased separately in digital format from several places online, they are also available in the compilation volumes of the main series.
My Soul to Lose
Trying to unwind, Kaylee goes out to the mall with her best friend. After having a strange panic attack where Kaylee finds herself unable to stop screaming, she ends up in the insane asylum. She begins thinking maybe she is insane, but after meeting several residents, things start to become clear.
This novella is told from the point of view of Tod, where he tells the story of how he became a Reaper. I enjoyed the fact that this novel gave a little more insight into the complicated relationship between Tod and his brother Nash; as well as giving the reader a little more background on the relationship between Nash and Sabine. This stand-alone novella relies upon the reader already knowing a bit about the already established world, so I would recommend reading at least the first novel in this series before reading this one.
Never to Sleep
Sophie is sick of her cousin Kaylee's cries for help. Kaylee's insanity is starting to make her peers question her own sanity. After Sophie finds herself in a horrifying world with creeping vines that feed off of blood, she starts to think that maybe Kaylee isn't just trying to get attention. In this novella, I found Sophie to be just as annoying as she was in the rest of the series, so I didn't enjoy the narrative much; however, the excursion into her point of view was interesting.
