Here’s a a little summary: Eleven-year-old Toby Steiner wants to do normal things on his vacation: he wants to hike and race his bike down the hill and learn to fish out on the lake. The last thing he wants is to return to the children’s hospital where his painful cancer treatment finally ended. When Toby starts spending time with Pearl, a spunky old woman who lives on a nearby farm, and Blossom, her broken-down cow, he sees all the more reason to keep the new lump on his side a secret from his parents. From Pearl he discovers the beauty of poetry, and from Blossom he just might uncover the meaning of life.
