1High-flying lesbionic brainiac Sid Rubin is caught up in the glow of new love--and the snowball fight of the century. Distraction in action, Sid forgets to duck and takes a full facial hit, launching her backward into Imani, who in turn slides down a hill, through a thicket, and amazingly, lands safely. Or so she thinks. Until she hears an ice crack and sees a fingertip rise through the small fissure. Cue the scream. Jimmy, Sid, Ari, and Vikram slip and slide their way to the rescue, somehow knowing that a chain of events has just been set in motion. The finger becomes a hand, and then a body. It's a young girl. And she's not alone. There are seven more skeletons―unidentified and unclaimed. When Imani utters the words, "I want someone to say her name," it's time for the posse to round up and ride again―chasing a mystery across time, and states, and even continents. A genetic genealogy hunt that's right up Sid's Silicon Alley. But there's a glitch in the system, because Sid's new girlfriend, Ava, has other plans. And Sid learns the hard way that before she can untangle someone else's family tree, she will have to find her own roots.
