Thanks. I have two trilogies and one stand-alone.
The stand-alone, The Faerie Dusters, is a fantasy coming-of-age about four fairies who get stuck in the human world of the late 1800s. Phrava is the magic of the fairies, and one of the disciplines is reading the rainbow. In the world of Phar Shee, a fairy's skin changes color to match his or her mental state: anger, passion, curiosity, etc. My original idea was, what if you could know what a person thinks by a color. I began with the mood ring, then thought of a peizoelectric tierra, and settled on skin that changes color.
In The Space Bum trilogy, the original idea was four men on a quest to rescue a lost prince. The MC is a character I've kicked around in my thinking for many years. He's an affable middle-aged man with a penchant for serendipity. He makes friends easily, and never gives up once he's set his mind. He is a mild-mannered character that does not stand out as much as the friends he draws to himself. He does have a past, and a guarded secret. He begins in his middle age, but by the second book, he is old and possessed by an alien life form. In the third book, he is a young man again, but in a life or death struggle with aliens that look like werewolves, and giant spiders. Currently, I am writing both a sequel and a prequel to this story line.
In my Star Seeder trilogy, my characters are based on deities, but with a twist. They are atomic immortals who seed planets with life, watch over them, and harvest the end result before the world ends. The story centers on the experience of the MC, an adopted son of the King, who works on the seed ship. I wanted to play around with a lot of religious topics and tie them into a hard science scenario.
