   Summary

   It’s both a blessing and a curse when William’s succubus blood awakens on the Noahtic. A blessing, because he’s never met anyone who feels as much like an old friend as his bondmate does. A curse, because a single feeding could give that brilliant man the tools he needs to destroy him.

   In order to sate his newfound hunger, William makes a distasteful choice.
