September Weekes is accustomed to teasing and bullying because of her white hair, tubby figure and silly name, but the discovery of a clear, smooth stone at her home casts her into a struggle between good and evil that will present her with sterner challenges.  The stone takes her to Gwlad, the Land, where the people hail her as the Cludydd o Maengolauseren, the bearer of the starstone, with the power to defend them against the evil known as the Malevolence. September meets the leader of the people and the bearers of the seven metals linked to the seven ‘planets’. Each metal gives the bearer specialised powers to resist the manifestations of the Malevolence; manifestations such as the comets known as Draig tân, fire dragons.  She returns to her home, but is drawn back to the Land a fortnight later to find that two years have passed and the villagers have experienced more destructive attacks by manifestations. September must now help defend Gwlad against the Malevolence.
Seventh Child is the first volume in a thrilling new fantasy series, Evil Above the Stars, by Peter R. Ellis, that will appeal to anyone who likes fantasy, especially fans of JRR Tolkien and Stephen Donaldson.  If old theories are correct until a new idea comes along, does the universe change with our perception of it? Were the ideas embodied in alchemy ever right? What was the basis of Celtic mythology?
Although ostensibly a fantasy for young adults, it is can just as easily be seen as science fiction, and will appeal to readers of all ages.
