Torrent (River of Time Series #3) by Lisa T. Bergren
Gabi and Lia Betarrini have learned to control their time travel, and they return from medieval Italy to save their father from his tragic death in modern times.

But love calls across the centuries, and the girls are determined to return forever—even though they know the Black Plague is advancing across Europe, claiming the lives of one-third of the population. In the suspenseful conclusion of the River of Time series, every decision is about life … and death.
