A Long Line of Cakes (Scholastic Gold‪)‬

Two-time National Book Award finalist Deborah Wiles introduces us to the Cakes, a family of traveling bakers, who've just arrived in Wiles's legendary Aurora County, Mississippi.
Emma Lane Cake has five brothers, four dogs, and a family that can't stay put. The Cake family travels from place to place, setting up bakeries in communities that need them. Then, just when Emma feels settled in with new friends... they move again.

Now the Cakes have come to Aurora County, and Emma has vowed that this time she is NOT going to get attached to ANYONE or ANYTHING. Why bother, if her father's only going to uproot her again?

But fate has different plans. As does Ruby Lavender, who is going to show Emma Lane Cake a thing or two about making friendship last.
