It’s a new term at Fernside boarding school, and Robin can’t wait for fun in the dorm, playing games and maybe even winning the coveted Form Shield. But for new girl Linnet, Robin’s younger cousin, there are just too many new faces and strict rules. Luckily, she has Robin for help and her very own hideaway.

And when the adorable puppy Rudy disappears, it is Linnet who is determined to find him. Even if it means dragging Robin and all her new friends headfirst into danger. There may be daring rescues, secret missions and adventures galore, but best of all are the true friendships to be made at Fernside.
