Fourth Dimension — Claire Ashleigh

Artist, Jenna Berenson, is devastated when her sister Maddy goes missing from Glastonbury Tor. While searching for her sister, Jenna accidentally steps into a time portal opened by Luke Marshall, an experienced Time Walker. He follows Jenna, who has been transported to Paris in the heart of the blood-soaked French Revolution.

Having narrowly escaped capture, Jenna links up with Luke, but refuses to return home until she has found Maddy. When the two are pursued by the Revolutionary Guards and race for sanctuary, Jenna is caught and faces the guillotine just as the blood lust of the populace crescendos to its murderous peak.
