Time Watcher by Kate Serzenta

Fix the past. Lose the future.

After an incident with a mysterious watch, Fabienne finds herself torn from her family – and married to the enemy. In a desperate attempt to restore her past, she entagles herself in a conspiracy with a secret time-traveling group that will change the course of a nation … and threaten
her unexpected, newfound love.

Time Watcher is an intricately woven, clockwork-tight tale, perfect for fans of Audrey Niffenegger’s The Time Traveler’s Wife and Diana Gabaldon’s Outlander series.
