Only Wrong Once

Two people die on opposite coasts — one in Los Angeles, one in Boston — with the same horrifying symptoms and no obvious connection. CDC epidemiologist Madeline Hamilton recognises what she is looking at before anyone else does: a lethal virus that should not be here, and did not arrive by accident.

She calls FBI counterterrorism agent Quinn Traynor, and together they uncover an imminent bio-terror attack. With the incubation clock running and only days before the infection outruns any containment, the two agencies must identify the carriers moving through American cities before a pandemic becomes unstoppable.

Only Wrong Once is the first book in Jenifer Ruff's FBI & CDC Thriller series — a fast, procedural medical thriller in which the science is as much a weapon as the manhunt, and the case ends up cutting far closer to home than either investigator expected.
