Just beyond the Gilded Age, in the mist-covered streets of New York, the
deadly Spanish influenza ripples through the city. But with so many
victims in her close circle, young socialite Allene questions if the flu
is really to blame. All appear to have been poisoned--and every death
was accompanied by a mysterious note.
Desperate for answers and dreading her own engagement to a wealthy
gentleman, Allene returns to her passion for scientific discovery and
recruits her long-lost friends, Jasper and Birdie, for help. The
investigation brings her closer to Jasper, an apprentice medical
examiner at Bellevue Hospital who still holds her heart, and offers the
delicate Birdie a last-ditch chance to find a safe haven before her
fragile health fails.
As more of their friends and family die, alliances shift, lives become
entangled, and the three begin to suspect everyone--even each other. As
they race to find the culprit, Allene, Birdie, and Jasper must once
again trust each other, before one of them becomes the next victim.
