When the Day Comes (Timeless #1)

by Gabrielle Meyer

I knew these things because I lived two lives simultaneously—one in 1774 and one in 1914. When I fell asleep in one path, I woke up in the other, back and forth, with no time passing in either one while I was away. It had been this way since the day I was born. But all of that would change on my twenty-first birthday when I was given the choice to forfeit one path and stay in the other forever.
