That's the blurb to Mike Feazell's book for younger readers, The Irregular Ones of Luemenor. It's the first of a series featuring lead character Max. Mike apparently has had a longstanding interest in children's literature, though any book that features unicorns on the cover has to be ten points down in youth cred. to start with.
I'm not sure there's a Christian subtext, but knowing Mike's background I suspect there has to be. But this much one can confidently say, it's gotta be better than his serious stuff for adults!
In any case, here's the Amazon Kindle link: The Irregular Ones of Luemenor: A Max Fletcher Adventure.
