Wow, I have 'rank's on Amazon. They're very very low, of course, but I have some :-)
'Man by a tree' (now only £5.36) Bestsellers Rank: 2,196,049
'The Bethlehem Fiasco' (now only £6.08) Bestsellers Rank: 3,034,912
'The Rage of Atlantis' (now only £6.75) Bestsellers Rank: 2,992,519
What surprises me is the 3rd has overtaken the 2nd. Is there something wrong with 'Jesus' books? Especially comedy?
