Please note that this review may contain spoilers for is prequel, Guardian of the Underworld. You can read my review of this novel [here].
Book of Light was written by Rachel Tetley and first published in 2015. It is the second instalment of the Underworld Chronicles and follows the continuing adventures of Jake as he trains to be the Guardian. The novel is preceded by Guardian of the Underworld (2014) and a third novel is planned for release later this year, though at the time of writing no further details have been announced.
It’s been a year since Jake Summers became the Guardian and since then he’s lived with a nagging fear that he’s not good enough. Even though he passed the five trials, he’s been without his Grandfather’s tuition and feels undeserving of his title. However, the time has come for his skills to be tested again. Disasters have begun to plague the Earth and this can only mean one thing. Lucifer has amassed an army and plans to destroy the world.
With his loyal friends Arianna and Will at his side, Jake heads back to the Underworld to receive his mission. The rise of Lucifer has been long foretold and there is only one thing that can stop him: the legendary Book of Light. There is only one problem. The Book of Light belonged to a previous Guardian and when he died, he took the secret of its location with him.
Jake teams up with the dragon Salazan and a bad-tempered puffle named Ferdinand and begins the dangerous trek across the Underworld in search of someone who knows the book’s location. However, his path is filled with danger. Giant spiders, dark spirits and cursed waters bar his way but these are far from the most dangerous things that Jake must face. An old friend has now taken a place at the head of Lucifer’s army and now will stop at nothing to kill him…
