Mac has left Gramps' diary behind in the future and Victoria Carmichael's ex-husband, Jeremy Bentaine, has stolen it along with Gramps' journals. Now, Bentaine Industries seeks to be the sole possessor of time travel technology... and that means eliminating Mackenzie Mortimer before he discovers the pocket watch! But Mac has followed Gramps' trail to WWII Nazi-occupied Belgium, where he must use his future technology to stay alive, locate Gramps, and unite a pair of star-crossed lovers. The horrors of WWII that Mac encounters will change him forever, but if the Bentaine family has its way, forever will be a very short time for Mackenzie Mortimer!
