Context - what the book's all about:
Legacy of the Mind is a fantasy romance novel (the first book in the Legacy trilogy) that brings a new concept to the fantasy genre; that people have skills split across three categories (mind, body and spirit) and using these skills they can just push the boundaries of what humans can normally do.
The concept of energy is central, both personal energy, and the energy at large in the world, and there is significant study into each. Each skill has an associated Temple, God, Academics, Councillors and ruling family (the Descendants), and the Descendants jointly rule the world.
The world has a prophecy where the Descendants must return a relic sent by the Gods in order to ensure energy stability for all time, however, when the fulfillment of the prophecy becomes uncertain, the world's population loses confidence, the energy dips perilously, and food supplies start to fail.
As the world teeters on the brink of crisis, Anita (the main character, a talented Body and Spirit) discovers a rogue object (a brass cylinder) in her subconscious. As she tries to uncover what it is and how it got there, she becomes embroiled in a struggle between two powerful groups, with two men seeking her affections, and begins to realise she's not who she's always been told she is.
Most important concepts / images that could inspire ideas - these don't have to be on the cover but are central concepts to the book:
Mind / Body / Spirit (could do some representation of this, or symbols for each area)
Descendants (could represent them by three family trees, or family crests)
The relic (looks like a big rock)
A brass cylinder
Countryside - especially centering around a river
Two covers I've seen that I think achieve the feel that I want to are:
A discovery of witches - http://www.amazon.co.uk/Discovery-W…004KA9VGA/
The husbands secret - http://www.amazon.co.uk/The-Husband…00BQ4NLC8/
