Wild Seed (Patternist, #1)

Doro is an entity who changes bodies like clothes, killing his hosts by reflex or design. He fears no one until he meets Anyanwu. Anyanwu is a shapeshifter who can absorb bullets and heal with a kiss and savage anyone who threatens her. She fears no one until she meets Doro. Together they weave a pattern of destiny (from Africa to the New World) unimaginable to mortals.
