Jacob's seven-year-old triplets are a handful. Allie is organizing her teacher to death. Jessie is crying in class. Meggie is becoming almost reclusive. Jacob is told what the triplets need is a woman in their lives. But he won't exchange girl trouble for woman trouble. Jacob's gone that route. It just got his daughters' hopes up--his hopes up--and ended in disappointment. Maybe the answer is to enlist the help of a friend, like his partner Michelle....

Dubbing his new triplet sisters "the Trips," nine-year-old Jacob studies them for a science project by watching them grow and realizes they aren't just "the Trips" anymore, but individuals he has come to love.
