Race for Freedom, Freedom Seekers Series by Lois Walfrid Johnson and published by River North.
Set in 1857, a group of children work together, despite their differences, to make a change and live out their faith. In Race for Freedom, a slave trader is hot on the kids' trail, forcing the Freedom Seekers to realize that because of a fugitive slave law, Jordan can be taken back into slavery even from a free northern state, and that if caught with a fugitive slave, Captain Norstad can lose the Christina. As they race to St. Paul the stakes high and the kids are all forced to make a choice . . . can they live the courage that offers life, liberty, and the pursuit of happiness to every person?
