Time Rift

What if you could change history by traveling back in time?On the evening of April 14th, 1912, the R. M. S. Titanic struck an iceberg and sank to the bottom of the ocean. Among the passengers who went down with the ship was Thomas Cole, a man who had been part of a conspiracy set up by J. P. Morgan to sink the boat deliberately. Seventy years later his grandson, David Cole, who leads an ordinary life, is about to change the course of history when he is confronted by a man named Keith Granger who was part of that conspiracy.
To redeem his own past Grainger allows Cole to travel back in time and save both his grandfather and the ship by giving him a time travel device. But the road is paved with many bumps as Cole's repeated attempts to succeed are not as easy as he thought.
