Dead Even book by Brad Meltzer 

Lawyer Sara Tate is in danger of losing her new job with the Manhattan District Attorney's Office if she doesn't get noticed fast. Smart and tough—a fighter who makes things happen—she grabs a high-profile burglary case that could make her career. There are two problems: Sara's husband, Jared, is the attorney for the defense . . . and she's been warned that if she does not get a conviction, Jared will be killed. What she doesn't know is that her husband has received a similar threat. Unless his client walks, Sara's life is over. Unaware of the stakes on the other side and forced to keep their secrets from each other, husband and wife become bitter adversaries, locked in a vicious head-to-head battle in the courtroom and at home. And there can be no victor in this struggle. No matter who wins . . . someone dies. Published By Harper on 2010-10-26
