JACOB WONDERBAR AND THE INTERSTELLAR TIME WARP

The third book in Nathan Bransford's clever and funny middle-grade science fiction series follows our hero, Jacob Wonderbar, as he deals with the repercussions of his travels in space.

Having returned home from another space adventure, Jacob and his friends are shocked to discover that their parents have reached old age and fifty years have gone by in a flash. They can use a time machine in order to set things right, but what if going back in time disturbs the universe and creates more problems than it fixes?
