The O'Sullivan twins return for their second term at St Clare's determined to work hard and do well. Most of their old friends are back again and there are new girls to size up. Among these are the twins' feathered headed cousin, Alison, the talented and friendly Lucy Oriel, and the surly and bad tempered Margery Fenworthy.

The twins are now firm friends with most of their form and form friendships with some of the second form also. As a result of this they are invited to a midnight feast with some members of the second form to celebrate the birthday of Tessie, a second form girl. Erica, an unpopular second former, resolves to disrupt the party after hearing herself discussed in unflattering terms when the others assume that she is not within earshot. The girls vote to ignore Erica after learning that she is the one who gave them away to Mam'zelle, causing Erica to vow revenge on Pat. She begins a campaign of spiteful tricks against Pat.

The twins arrive at St. Clare's ready to work and play in the summer term as they enjoyed at Redroofs. Will Bobby change and will Carlotta's secret comes out?

Someone has stolen the witch of Crookhaven's horse, and there will be no peace in the village until it is returned. So bold, brassy Kate O'Sullivan takes matters into her own hands. But instead of saving the day, she manages to land herself--and her family--in trouble with the king. So Kate sets out to save their hides the only way she knows how--with a good story. Filled with imagination, wit, and a healthy helping of good old-fashioned Irish blarney, this is a hilarious tale that will keep readers coming back for more.

The Second Form at St. Clare's is the fourth novel in the St. Clare's series of children's school stories by Enid Blyton. The series is about the boarding school adventures of twin girls Patricia and Isabel O'Sullivan. Their form mistress is now Miss Jenks and they no longer have to bear the severeness of the first form mistress, Miss Roberts – who is extremely sarcastic and firm but can be kind when she feels like it, a bit like Mam'zelle, the French teacher that used to teach and is still teaching the girls.
