Queen of the Sylphs - EN - L.J. McDonald - Paperback

Sylph, book 3 of 4, completed series

It was a dream come true. Solie had her own battler, a creature of almost infinite magic who could vaporize legions in the blink of an eye and would willingly suffer a thousand bloody deaths to protect her. She was his love. More simply, she was his queen. 

Many others feel the same. The new-built settlement is a haven for all. Erected by sylphs of earth and fire, air and water,  the Valley is Solie's dominion. But, lovers without peer or killers without mercy, the very nature of their battler protectors means peril. It is not in any sylph's nature to disobey, and while some are hers to command, others are the slaves of Solie's enemies, the jealous, the cruel. Those who guard her must not fail. Their peasant-born ruler is not yet safe as, Queen of the Sylphs.
