This is book two in this series, and I highly recommend you read them in the order written, to fully understand what is going on in each book. The description on Amazon described this book so well, that I have used part of that review below:

"What if you were studying for your Ph.D. in archaeology and somehow got trapped in first-century Jerusalem after a controversial physics experiment went horribly wrong?

What if you knew from your history books that a kind and decent man was going to be murdered by the powers-that-be, all because of stupid politics?

It’s A.D. 57 and Rivka Meyers desperately wants to go home, but her husband Ari is a physicist, and he says they’re stuck in the first century. He also says that the laws of physics say Rivka can’t change history. Rivka knows he’s wrong, and she’s going to prove it—by saving James the brother of Jesus from being murdered by the evil high priest.

Premonition is a time-travel suspense novel that mixes science, history, religion, romance, and adventure. It’s about becoming the person you were meant to be. It’s about learning to accept harsh reality when you’d really rather quit and go home. It’s about being a fighter for justice, even when you’re fresh out of easy answers to hard questions."

I don't read much "time-travel" books, but must say this series has grabbed my interest and held it. Now on to book 3 in this series, "Retribution". ( )
