Aftershock by Judy Melinek

When an earthquake strikes San Francisco, forensics expert Jessie Teska faces her biggest threat yet in this explosive new mystery from the New York Times bestselling authors of Working Stiff.

At first glance, the death appears to be an accident. The body, located on a construction site, rests under a collapsed beam. But when Dr Jessie Teska arrives on the scene, she notices the telltale signs of a staged death. The victim has been murdered. A rising star in the San Francisco forensics world, Jessie is ready to unravel the case, help bring the murderer to justice and prevent them from potentially striking again.
But when a major earthquake hits San Francisco right before Halloween, Jessie and the rest of the city are left reeling. And even if she emerges from the rubble, there's no guaranteeing she'll make it out alive.
With Melinek and Mitchell's trademark blend of propulsive prose, deft plotting and mordant humor, this electrifying new installment in the Jessie Teska Mystery series offers the highest stakes yet.
