Thanks for asking!
All About Elfland and the next two books are based on the idea of an ancient race who live among us and also inhabit other layers of reality. Not the most original concept, but it's what you do with it, right?
The setting of AAE is contemporary and it's based around two families and two houses - the Foxes, a loving, mostly happy bunch who live in the valley and the Wilders, a fractured, dysfunctional lot who live in a cold, scary mansion on the hill. (I like the idea that, never mind parallel worlds, every single household is like a different planet!) They're members of the ancient race, but live like humans, among humans. Lawrence Wilder is the 'Gatekeeper' to the Otherworld, but he's mysteriously 'locked' the Gates against members of the elder race going in or out, so they are mightily ticked off with him and there's a gradual revolt gathering against him. Against this background, Rosie Fox falls in love with the younger Wilder son, Jon. When he fails to return her affection, on the rebound she marries a human, Alastair. Realising she's made a horrible mistake, she begins a disastrous affair with the older Wilder son, Sam, who's a bit of a dodgy lot and just come out of prison for manslaughter. When Alastair finds out, he wreaks ghastly revenge on Rosie's beloved younger brother, Lucas, who happens to have a secret connection with Lawrence...
Anyway, there is loads, loads, loads more than that to it but that sums it up fairly well. A lot of it is about conflict between those of the ancient race who want to live in peace with humans, and those who don't. And it's got lots of passion and sex and intrigue, too!
I do happen to know, though, that the manuscript I delivered was miles too long. Like 70,000 words longer than specified in my contract. And I'd already cut out 30,000 before I even delivered it! So I'm waiting anxiously to hear from my editor. I hope his ideas for cutting the wordage don't conflict with mine!
