Magic in the mix
Life seems to be back to normal for "newly twinned" sisters Miri and Molly until their magical house sends them on new time-traveling adventures, including meeting Molly's mother in 1918 and saving two unusual soldiers during the Civil War.
Twins Miri and Molly long to time travel again. They find a portal to the Civil War, but their brothers find it, too--while wearing Civil War reenactment costumes!
