Hellhole Inferno kept up the suspense, action, drama and horror of the previous books. The 'movie scene' chapter style is engaging, keeping you turning the pages to see what is happening to the other characters on other planets. The way all three books have tied in to each other is truly impressive, but you wouldn't expect anything less from two great authors with a pedigree such as Kevin J. Anderson and Brian Herbert.
I would highly recommend this series to any sci-fi and fantasy fans. A very solid 4.5 out of 5 stars.
