"Trille's best friend, Lena, lives on the other side of a hole of the hedge in Mathildewick Cove, where hardly a day passes without the two of them inventing some kind of adventure that often ends in trouble. Trille loves to share everything with Lena, even Auntie Granny's waffles, but Lena is keeping a secret that could compromise their friendship. Trille knows that Lena is his best friend, but does she feel the same way about him?''--Publisher.
