Time-travel adventure for MG readers > Likes and Comments

Two young teens--a brother and sister-- find themselves flung back in time in the Timekeepers series of books. The first adventure, A Revolutionary Tale, finds them on the cusp of a small battle in 1777. The siblings don't understand what's happening, or why, not to mention wondering if they'll ever get back to their own time.
Subsequent books take them to a pivotal day in 1865 (Civil Disturbance), to the place where gold was first discovered in this country (Good as Gold), and back to a day in the midst of WWII (Computer Zero).

Timekeepers.... by author J.Y. Harris.
