Unwitting time traveler Joseph Bridgeman is adjusting to life in the present. When he's contacted by The Continuum, an organized group of time travelers based in the future, he learns his career is just getting started. One of their operatives is missing, last seen in nineteenth-century Paris, and they believe Joe's ability to see the past might be the only way to find him. Teamed up with Gabrielle Green, an acerbic, wisecracking traveler, Joe heads back to a burning opera house in 1873. How will Joe succeed when Gabrielle clearly hates his guts, the missing traveler disappears the second anyone sees him, and a familiar foe threatens to trap them in the past for good? With help from his best friend, Vinny, and the mysterious clues in his sister Amy's paintings, Joe must figure out a way to complete his mission before the blazing inferno comes crashing down around them all--Adapted from book jacket flap.
