St. Clare's: The Twins at St. Clare's & The O'Sullivan Twins

At St Clare's boarding school, life is rarely dull for the O'Sullivan twins, Pat and Isabel. Their peace is disturbed when Claudine, a bold new arrival whose family ties to the school run deep, turns up with plans for mischief and rebellion. The twins are drawn to her daring, but the question is whether she will manage to stay the term. Elsewhere in the school, the fifth formers are growing up yet still up to their old tricks, and the sixth form faces a new challenge when the twins are made head girl. Pranks, friendships and rivalries fill the pages of this lively school story.
