Philip Witvliet of the Grimdark Reader lavishes Michael J. Sullivan’s Hollow World with praise, awarding it a 4/5.

This has received a lot of hype and praise, which it largely lives up to. While not my primary genre, this is a strong science fiction book, complete with time travel 2000 years into the future and a type of hybrid human. Loaded with great pop culture references, the same consistent, solid writing that made The Crown Conspiracy and other Riyria books a pleasure to read, and great characters, science fiction fans can not complain about anything in this book. I have read quite a few science fiction books in the past and this definitely ranks in the upper echelon in terms of quality and fun. 

Highly recommended for science fiction fans. Also recommended if you are new to science fiction or even if you don’t necessarily consider yourself a fan of the genre, still try this because in terms of story enjoyment and literary value, this is a great book!
