The name of the person who wrote it is Louisa May Alcott.
The book was about a family and their dad was at war. The girls names are Meg,Jo,Amy and Beth.
One day they found out there was a young gentlemen living next door in his grandfather's house.
His name is Laurie (the Laurence boy). Then the next day Meg and Jo got an invitation to a party.
At the party Jo was shy so she went to a room were she thought no one was. Then someone said hi. She turned around there standing was the Laurence boy.So they talked the rest of the night.
(and I can't tell the whole story so I will skip to the end.)
Meg has twins and Jo is dating. The best part is their dad is home!
