Casey Donovan has issues: hair, height and uncontrollable trips to the 19th century! And now this-she's accidentally taken Nate Mackenzie, the cutest boy in the school, back in time. Awkward.
It's the eve of the American Civil war and protocol pressures Casey to tell their hosts that Nate is her brother. No one more surprised than she is when they are forced to share a one room worker's cabin. Super awkward.
Nate's slow to accept their new reality but when he does, he realizes he needs Casey to get back. His nearness is intoxicating to Casey, but she keeps her cool by hanging a privacy blanket and staying aloof. Knowing Nate has an evil girlfriend waiting for him at home helps.
Over time Casey gains the attention of a handsome, wealthy (and unwanted) suitor, and something changes in Nate. Are those romantic sparks or is it just "brotherly" protectiveness?
When they return to the present, things go back to the way they were before: Casey parked on the bottom rung of their school's social ladder and Nate perched high on the very top. Except this time her heart is broken. Plus, her best friend is mad, her parents are split up, and her younger brother gets escorted home by the police. The only thing that could make life worse is if, by some strange twist of fate, she took Nate back to the past again.
Which of course, she does.
