Young Adult Trope - Time Travel

If you're a fan of the Outlander series by Diana Gabaldon, you should read the Breaking Time duology by Sasha Alsberg. 

My favorites on this list are Proof of Forever by Lexa Hillyer and Stolen Time by Danielle Rollins, which is the 1st in a 3 book series. 

Throwback by Maurene Goo is still on my TBR list.
