Det här är Demonataserien av Darren Shan .
Serien handlar om tre barn (citerar från Wikipedia):
The series centers around three protagonists: Grubitsch "Grubbs" Grady, Cornelius "Kernel" Fleck and Bec MacConn. Although they meet each other at various points, they are from separate times; Grubbs lives in the present day, Kernel in the 1970s and Bec in around 450AD.
Och det handlar om en lång konflikt med ett parallellt demonuniversum:
The books detail their fight against the evil demon master Lord Loss, his many demon familiars and the mysterious Shadow, who promises to destroy the human universe and to even stop death. Together with The Disciples, the main characters thwart the Demonata's attempts at world destruction multiple times.
Texten du citerar är från den tionde och sista boken Hell's Heroes:
Clearing my throat, to a chorus of good-natured groans from Kernel and Bec, I chant solemnly. “In the beginning Grubbs created the heavens and the earth, and everything was dark. Then Grubbs said, ‘Let there be light!’”
And there was light.
Coolio!
