One of my new favorite series: River of Time series by Lisa T. Bergren. I've had these books sitting on my TBR pile for several weeks and just got around to them a few days ago. Gotta say, I read one a day. Couldn't stop. Seriously. They're that good.
Waterfall (Book 1)
While most American teens would kill for an Italian vacation, the Betarrini sisters have spent every summer of their lives there with their archaeologist parents. And they’re not happy to be back. Stuck on yet another hot, dusty dig, they are bored out of their minds…until they place their hands atop handprints in an ancient tomb and find themselves catapulted into the Fourteenth Century. Gabi emerges in the middle of a dream–or nightmare?–with hot Italian knights in a fierce battle. And so begins her quest to return home…while wondering if she wants to at all.
Cascade (Book 2)
Gabi knows she’s left her heart in the fourteenth century and she persuades Lia to help her to return, even though they know doing so will risk their very lives. When they arrive, weeks have passed and all of Siena longs to celebrate the heroines who turned the tide in the battle against Florence—while the Fiorentini will go to great lengths to see them dead. But Marcello patiently awaits, and Gabi must decide if she’s willing to leave her family behind for good in order to give her heart to him forever.
Torrent (Book 3)
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 this suspenseful installment of the River of Time series, every decision is about life … and death.
There are two companion novellas that go along with the series (Bourne and Tributary). They are waiting on my Kindle as we speak, up next! Can't wait! :)
