Zero Sum — G.K. Parks

A dead security guard and a missing client are just the beginning... Alexis Parker's temporary relocation to sunny California isn't something she ever saw coming, just like the homicide victims she stumbled upon while conducting a security check. Before she can even call for help, Alex realizes the shooters are still inside the building and she's the only one around to stop them. But showing up to a gunfight without a gun is foolish, if not downright suicidal, and she made Martin a promise that she'd try to be more careful. So she does her best to slow them down, but the authorities arrive too late. With the shooters on the run, Alex can't help but get caught up in a murder investigation that turns into something much worse than she thought possible. Her client has vanished. His assistant says it's due to a family emergency, but that doesn't track. Everyone has secrets. But in this instance, Alex isn't sure which will prove fatal. All she knows is there's a clock on this case, and if she doesn't figure it out in time, the consequences will be catastrophic.
