When All is Null and Void

When Caleb Carlisle is recruited to be a time manipulating artifact collector, it is not for the usual purposes of artifact extraction. The dimension all Timewalkers pass through to reach their destinations is leaking throughout history, infecting them with a disease that renders them rabid killers. Rhea James, the Queen of Time, has charged Caleb with assisting her to close the leaks.

First, though, Caleb must learn how to Time Hop and is sent to 2014 from the 22nd century to live with his new mentor. An incident with a high schooler named Danielle Baker leaves Caleb's abilities in troubled water, and when the Queen of Time is convinced Danielle is the key to fixing their problems, Caleb grows determined to keep his friend from simply being a tool to defeat evil.
