The Elixir — Lori Soard

The dark parking garage with the dead body of his friend and mentor only begins Jake Walker's problems. Soon, he is the prime suspect in Benjamin Monroe's murder and worried that his best friend, Ben's daughter, will believe the worst. Celeste doesn't know who killed her father but she does know one thing-it wasn't Jake. As she and Jake set out to find the killer, they discover that her father unlocked the code to a fountain of youth formula. Anyone who wanted the formula could have killed him, and it was worth millions. During their investigation, they uncover more facts and more bodies. Because they show up at every crime scene, the detectives investigating the case suspect Celeste and Jake of murder. The two go on the run until they can clear their names. But, there are more sinister forces at work than either realizes, and the deception runs as deep as the national government...
