Elementals 4: The Portal to Kerberos, Hardcover/Michelle Madow

She will venture into Hell to save the one she loves. After being betrayed by one of their own, Nicole watches helplessly as Blake is snatched into the prison world of Kerberos-along with Medusa's head, which is the one item they need to stop the Titans from rising again. Now Nicole and the other Elementals must enter the portal, find Blake, and bring him and Medusa's head back to Earth before the deadly monster Typhon returns and wreaks havoc on the world. But there's one catch-their elemental powers don't work in Kerberos. In a dimension designed to make those within it lose touch with reality, and that's filled with dangerous creatures who want to stop them from completing their task, will they make it out alive? In this penultimate book of Nicole's story, join the Elementals as they journey through hell to save the world... before it's too late.
