I know of David Skibbins and his thriller / tarot linked novels, and also Piers Anthony tarot trilogy.
Wouldn't it be great if an author did a series of novels with each book based on one of the Major Arcana? A bit like Sue Grafton has done with the alphabet series
'Five of Cups' by Wendy Mewes - she's a TABI member and may even be a member of this forum.
It's about a lady who goes to live in rural France following a relationship break up, she has a tarot reading and the 5 of Cups shows up..
Very good, I'd recommend it.
Someone ought to take it upon themselves to update, or at least make some additions to, the Tarotpedia entry for novels and fiction, terribly out of date.
