I'm always simul-reading multiple nonfiction books for work, but for pleasure I am currently working my way through two fiction series:
- James Rollins' SIGMA Force series (I'm currently up to book 7.0, The Devil Colony)
- Charlie Higsons' The Dead series (I'm currently up to book 3.0, The Fear)
When I finish these series, I'll read a non-fiction title or two for pleasure, then dive into another fiction series.
