Grim Haven (Coffee And Blood, #8)

Save Sanctuary, save the world.
If Drest thought pouting would help, he would brood like the vampires from fiction. His first full night with Cae begins exactly as he expects, cozy, awkward, and a little bloody. But alarm bells go off and they find themselves in a fight to save Sanctuary.
The Lamia want to gain entrance, the boundary is failing, and the Council are sitting on their hands, hoping Drest fails.
Their enemy has knowledge about Sanctuary which no mortal had the right to share, but important details were left out. The Lamia don't expect the citizens of Sanctuary to fight back, let alone for them to work their magics together.
Vampires underestimate the power of alliance. It's a mistake they will pay for.

Aya DeAniege is a Canadian author who wrote for years, first to please herself then writing stories for free--believing no one would ever pay to read her stuff--before pursuing indie publishing. She still writes mainly for personal pleasure, with topics ranging from romance, fantasy, science fiction, on to whatever takes her fancy in the future. World creation fascinates her, and when she finds one she likes, she dabbles endlessly.
