Since summer was six years old she lived with dear Aunt May and Uncle Ob. Now, six years later, Aunt May has died. Summer, who misses May with all her might, is afraid something will happen to Ob. Most days Ob seems like he doesn't want to go on.
But then Ob feels May's spirit around him and he wants to contact her. Cletus Underwood, a strange boy from school, reads about someone who could help him do that. Summer wants to hear from May too.
Ob and Summer don't know what to expect when they set off on their search for some sign from May. They only know they need something to ease their sorrow and give them strength to go on living—always knowing they will never stop missing may.
