Children of Poseidon - Annalisa Carr

Poseidon's son Rann has been content to rule his island paradise for centuries, but now something dangerous is stirring in his seas. A dark web of evil spreads from the horn of Africa to the covens of London. A call for help from her old coven gives young witch Jewel a reason to leave her island home and her crush on Rann, and hurry back to London where old crimes are rising to disturb the city's magic community. The past is about to collide with Jewel's present and threaten her future with something far more lethal than unrequited love.
