Nicki (American Girl Today)

Nicki Fleming is a natural with animals. When the chance to train a service dog comes up, she just can’t say "no," even if it means taking on more responsibility and having to give up some of the things she loves doing. When Sprocket the puppy turns out to be a handful, Nicki has to muster all of her compassion to continue his training. She knows that one day Sprocket will make someone else’s life better--and that makes all the difference.
