Elements of Magic is the second book in the the Demon's Covenant series. Held by Magic must be read first. Full description coming soon. This reverse harem urban fantasy series is filled with fast-paced supernatural action, magic, adventure and romance, all led by a kickass heroine with a very British sense of humour. These books are set in the world of LJ Swallow's The Four Horsemen series but with different characters and a separate storyline. The two can be read separately.
