    Giant chickens, rats, and insects run amok, and children given the food stuffs experience incredible growth--and serious illnesses. Over the years, people who have eaten these specially treated foods find themselves unable to fit into a society where ignorance and hypocrisy rule. These "giants," with their extraordinary mental powers, find themselves shut away from an older, more traditional society. Intolerance and hatred increase as the line of distinction between ordinary people and giants is drawn across communities and families. One of H. G. Wells' lesser-known works, The Food of the Gods has been retold many times in many forms since it was first published in 1904. The gripping, newly relevant tale combines fast-paced entertainment with social commentary as it considers the ethics involved in genetic engineering.

    On this occasion, however, they’re right up against it. A loaded gun has been left behind in Ancient Egypt and it’s up to them to retrieve it before anyone accidentally blows their own head off, thus affecting the timeline for centuries to come. And as if that’s not enough, someone (Max) has inadvertently poisoned Mr Markham. It’s hot, they’re running out of supplies, they can’t find the gun, and it’s all going horribly wrong. Again.
