In Their Blood — Sharon Potts

Born into a life of privilege, Jeremy Stroeb loves freedom, loathes responsibility and drops out of college to start backpacking across Europe. But this free-spirited drifter crashes back to brutal reality when his parents, Rachel and Daniel Stroeb, are murdered in their home on Miami Beach. When he returns to Miami, Jeremy assumes guardianship of his teenage sister, Elise, who is traumatized and convinced the killer will be back for her. With steely, urgent resolve, Jeremy vows to find out what really happened to Rachel Stroeb, the respected CPA and Daniel Stroeb, the controversial professor. Determined to get on the inside of his parents' lives, Jeremy takes a job at the accounting firm where his mother worked, and enrolls at the university where his father taught. But too many details don't add up. With mounting certainty that his parents were anything but the people he thought they were, Jeremy must face the toughest questions of all. Who were Rachel and Daniel Stroeb? And when will the killer be back for the next of kin?
