The Crimson Hour (The Timeslip Series #2)

Eloise Popescu has one last entry to make in her screw-up-alog, and it's a doozy: she has just walked into the cross-fire of warring Chinese mafia families and into the path of Hanes Reynolds whose career has just been ruined by those same families. As Eloise and Hanes reluctantly unite forces to escape the clans, they must learn to trust one another … or repeat the fatal mistakes they made the last time they were together in 19th-century Hong Kong.
