The Book is the fifth studio album by Czech black/heavy metal band Root, released on 24 June 1999 through Redblack Productions.

MetalUnderground.com gave it a 4 out of 5, stating: "The Book seems more focused overall than The Temple in the Underworld, keeping up the unique style but not going nearly as eclectic.

The sound is based in doom and a constant mid-tempo pace, and is overall a bit more mature and advanced than the earlier albums.

Unlike with its predecessors, almost none of the album can even be remotely considered black metal anymore, as Root went a far different direction than the infamous second wave.

Vocally, the disc usually sticks to a deep and clean baritone singing that can't really be heard anywhere else".
