The Children of the Pantheon (Twilight of Kerberos: The Final Adventure)

IT ALL ENDS HERE!
Kali Hooper knows how to save her world. She must unite the ‘Four’ and the magic they carry with the old Race artefact known as guardian Starlight. But there’s a problem – Kali’s dying, stripped of her essence by Querilous Fitch, who plans to use it and the artefact for his own terrible ends. In the heavens, meanwhile, the final battle between Kerberos and the Hel’ss, and beneath their glow, Twilight goes insane.
Gabriella DeZantez, Silus Morlader and Lucius Kane join Kali on a final, explosive journey from the ruins of Scholten to the mysterious Congress of Ether, to the shores of an island of diamond and into the haunted void of the Expanse. Armies will clash. Churches will fall. Men and gods will die.
