Destroyer of Worlds. The Fated Chronicles, #5

Truth is the most powerful weapon there is, but only if you dare to believe... Contemporary Portal Fantasy AdventureAfter Colin flees with Catrina, he meets up with someone he never thought he'd see again-the one man who might be able to tame this dark magical power everyone is so afraid of. But this help comes with a severe warning: if the power cannot be contained, it must be destroyed! Did they flee one prison only to end up in another? Meanwhile, Meghan is closer to home than she's been since the quest began but finds herself a prisoner on an island protected and hidden by a magical force field, with no chance of escape. She makes one discovery after another, secrets and lies unraveling, each more mystifying, horrifying, and unbelievable than the last.
She's battered, broken, and stuck in a world she's no longer sure she wants to be a part of, but has no escape from. And when something utterly heartbreaking shatters everything she's come to believe and crushes the faith in those she's trusted most, rescue arrives in the form of someone she never thought she'd see again with an offer she might not be able to refuse.
