Toby was formed in a laboratory with a mixture of cat and human DNA--hence his delineation as a Trilby--by six scientists who have spent the past 40 years in an underground cavern to escape the presumed destruction of the world. As Toby turns twelve, he embarks on an odyssey to find out if he has a soul, venturing out into the world above for the first time. His journey introduces him to various characters, and he learns about himself along the way. This short but powerful story blends several genres--Christian fiction, science fiction, post-apocalyptic fiction--while presenting a relevant contemporary message infused with hope, making it appropriate for younger readers as well as adults.
