Time Will Tell Series by Les Lynam

Sean Kelly considered himself an average 16-year-old, living in an average neighborhood in a small University town. Nothing too exciting ever happened in Grover's Corners, Missouri; some might even label it boring. His ordinary life was disrupted when a distant relative dropped by at the beginning of his Junior year in high-school. A distant relative from the 23rd Century.

Sean Kelly and LX travel back one more generation to the year 1969. The question is: will either teen know how to 'make the scene' in the sixties? Can they blend in with the other teens in tiny Mercer, Iowa; including Sean's dad? When they return to 1995, both of them have regrets about the past.

After her relocation from 1969, Jane joins LX and Sean in an attempt to kidnap a clone from the Schattenwelt space station in the year 2169. Sean is shocked to find that he has already been there twice, but even more surprised by the team leader.
