I have never heard of Leech (Ennes) or Starter Villain (Scalzi) but both sound intriguing in completely different ways. It’s been a while but you might just have gotten me to start reading something longer form again.
Also, massive props for not just including some of the main books in the series starting with Leviathan Wakes but for also including Gods of Risk and The Churn on here. The Expanse is so compelling that those novellas really add an extra something special!
