Entering adolescence, the Tinys return to their beautiful, restored world only to discover that human shortcomings can undermine happiness and ruin friendships. Sadly, there is also a major problem the Professor can't overcome and tears begin to flow. Hoping to showcase Paradise to his colleagues, will the indication of suffering turn the world against his experiment?

Within the Greenville University, a challenge from the Professor drives Seth to compile convincing evidence that God exists. A close friendship develops as the scientists discuss various matters: Is there a purpose for suffering? Why does God allow natural disasters to occur? What is human nature and why did God make us this way? And why were Christian scientists able to discover so many universal laws of nature?

After a reluctant interchange over 'freewill' the Professor begins to view God's justice in a new light, but nothing prepares him for the devastating choice a few Tinys make when Uncle Louis' back is turned.
This is the second book in The Enormous Tiny Experiment series. The third book Treasure in Paradise  is currently (December 2021) being prepared. The series is primarily written for young adults but has caught the imagination of a much wider audience.
