Kaitlyn and the Competition

Thirteen-year-old Kaitlyn Perez is a very professional and well organized babysitter, but suddenly she finds herself in competition with a boy and the only thing she knows about him is that his nickname is Doc, he lets the kids he is babysitting run wild, and he is probably in her class--and that is only the beginning, as the stress causes her to quarrel with both her best friend, Piper, and her sister, Eve.
