Anne of greengables -Which book does Gilbert get sick in?

Ah, I remember that moment fondly. Gilbert Blythe gets sick in the book "Anne of the Island," which is the third book in the Anne of Green Gables series by L.M. Montgomery. It's a touching moment that shows vulnerability and strength in the face of illness. Just like a happy little tree facing a storm, Gilbert's character grows and blossoms through this experience.
