Tattoo

Her fate is in her flesh.
In an environmentally fragile world where human and animal genes combine, the rarest mutation of all — the Trader — can instantly switch genders. One such Trader — female Sorykah — is battling her male alter, Soryk, for dominance and the right to live a full life.
Sorykah has rescued her infant twins from mad Matuk the Collector. Her children are safe. Her journey, she believes, is over, but Matuk’s death has unleashed darker, more evil forces. Those forces — led by the Collector’s son — cast nets that stretch from the glittering capital of Neubonne to the murky depths below the frozen Sigue, where the ink of octameroons is harvested to make addictive, aphrodisiac tattoos. Bitter enemies trapped within a single skin, Sorykah and Soryk are soon drawn into a sinister web of death and deceit.
Kirsten Imani Kasai
Kirsten Imani Kasai, a native Coloradoan, has lived in places as diverse as Newark, New Jersey; East Hampton, New York; Bradford and Penzance, England (sadly devoid of singing pirates); and a windowless cubby beneath the stairs in a San Francisco flat crowded with ten roommates, four iguanas, three cats, two German exchange students, and a bald illegal Irishwoman, none of whom possessed a front door key. Before having children, she moved to a new city every six months, indulging her taste for novelty. She currently resides in southern California with her husband and two children.
