The Crossing Hour - a time travel novel by Quoleena Sbrocca

http://www.amazon.com/dp/B00S3786C6

"Time travel is completely bogus and entirely unbelievable as a premise, but Sbrocca takes the concept and convinces me of its truth. She gives underlying scientific technological explanations that had me believing in her time travel theory being plausible. And who better to travel through time then the historical figure she chose! Sbrocca’s premise and usage of time travel were both clever and riveting. The author chose a good idea and then made it into an excellent book." -Goodreads.com review
