When an Aryan baby is born to a Muslim woman living in Copenhagen, her husband’s family shuns her. But DNA tests prove Sorraya’s fidelity. And she is just the first in what soon becomes a rash of similar cases across Europe, threatening widespread social change even as they ignite passions in immigrant communities and incite familiar racial hatreds. What mysterious conspiracy connects a retrovirus, a young slacker biogeneticist, a former punkette, a dogged reporter, and pharmaceutical giant Keoxis? Clarke delivers a contemplative slice of near-future science fiction paced like a thriller but full of probing questions about our prejudices.
