Z Eternal - The Z Infection, #1

Sheriff Brody Johansen is overworked, under-budgeted and falling in love with one of his deputies. So the last thing he needs is to find grave robbers have struck an out-of-the way cemetery. What he discovers about the missing bodies links them to a mysterious lab that set up in his county a few years earlier. Before he knows how it's all tied together, he's faced with a situation he can hardly believe:  an infection is spreading, turning anyone in its path into mindless, flesh-craving freaks.
Brody joins forces with a scientist from the lab and a shady man who worked for the lab's owners to fight the rising tide of the undead-and his feelings for the unobtainable woman under his command. They might have a future together after all, if they can survive.
