Lowell Park (novel): Set in 1990, Jenny Brix lives in Iowa City.  She is a history buff.  She even has a Ronald Reagan picture when he was in his 20s as a lifeguard!  When she goes to a meeting, a very old professor has a heart attack.  Panicking, she uses CPR on him, thus saving his life.  After a few stops to the hospital, he asks her which US president she likes best.  She answers Ronald Reagan.  So then the professor tells her that she can go back in time and meet him.  She is shocked, but the professor keeps telling her it's true.  She finally believes him, sort of.  The professor takes her to Dixon, Illinois, Reagan's childhood home.  There the professor tells her she has 80 hours to stay out of the timezone, or her body will be used to the other timezones and can't come back to present day (1990).  When she goes into the time machine, it actually is set on 1832, instead of 1932 (where she was going).  She then meets Abraham Lincoln (who develops a little crush on her), and Chief Black Hawk during the Black Hawk War.  After all of that is straightened out, she goes to 1932 with less than half the time left she started with.  Once she gets there she sees a young, handsome Ronald Reagan going past her to save a person from drowning.  She then gets some friends, Scooter and Betsy.  They say there is a dance at Dixon's run down, old high school.  There she dances with Ronald and his brother.  While dancing with Ronald, she falls down the steps with him.  They then get a crush on each other.  After going on a few dates, she has to go to her original timezone.  She and Ronald have a sad exchange (Ronald doesn't know about the time traveling) when she has to leave.  Jenny then takes Scooter and Betsy to Lowell Park, where she shows them the time machine.  She then leaves, leaving the others dumbfounded.  When she comes back, professor says he is Scooter, and spent the rest of his life finding things about the time machine after she left until he finally made the time machine.
