What is it about teenage girls that attracts time travel? Samantha DeVries in Connecticut has enough pressure already. Her father's Olympic dreams were shattered with an injury, so now he intends the plucky girl to be the first African-American to compete in a riding class at the Olympics. Sam loves horses, so she trains non-stop, and she takes judo classes and socialises at the country club.

TURNING ON A DIME then introduces us to Caroline Chandler, a girl growing up in Mississippi in 1863. She loves her own horse Pandora, and she just takes it for granted that some of the people on the property are her family's slaves, because she's never known anything different. The war between the states has been raging for two years, and troops on both sides are in need of remounts. Caroline wants to safeguard her beloved horses, even more than she wants to escape her restrictive crinoline garments.

When the girls meet, Samantha has taken a trip to stay in a period house and she thinks the old-fashioned dress of the girl who wakes her, is because she's recreating 'Little Women'. Caroline has not seen many biracial persons and assumes that Samantha is a slave. The girl freely admits to being a slave in the barn, but claims to own a horse - impossible. Samantha realises that the creaking old live oak trees draped in Spanish moss, have become saplings while she slept. Not only that, her phone can't get service.

"I've paid scant attention to Mom's lessons on emancipation, Rosa Parks and the civil rights movement, figuring that we've all moved beyond it," says Sam. "But now I'm in a time warp, and it's ugly." Caroline is separated from her family and the Union soldiers take over her house. The two girls learn to work together and stand strong, even in desperate circumstances. "I can't change history," says Sam, which is odd considering that she has been doing her best to change it.

We are told that about a million horses were killed during that awful time of conflict. There's lots to learn in this fast-moving adventure tale and I cheered on the great characters as they tried to survive and keep their beloved horses alive. Maggie Dana has given us a heroine to remember in Samantha and a girl ahead of her time in Caroline. Young adults of many interests, but especially those who like horses, will revel in TURNING ON A DIME.
