The Expanded Earth by Mikey Please

One sunny Sunday, without warning, humankind is reduced to the height of a handspan - an unsightly transformation as potentially fatal as it is inconvenient. On a remote coastal path, Giles awakes in his new body to discover a world reshaped and magnified into a place of astounding abundance and deadly peril. Desperate to reconnect with his loved ones, he seeks the help of fellow survivors, and together they embark on a quest across the altered landscape. But as their journey unfolds, the more the question persists - are they still truly human, or has their reduction in size marked the beginning of a descent into savagery, an evolution into something other? Elsewhere, one week earlier, Professor Elizabeth Goodwin makes a monumental discovery - God is alive and physically among us, but not in the form we've been taught to expect.
