Not this one - but I have a contemporary fantasy nearing completion that is heavy mythology/religion in a mash-up sort of way.

Ancient Egypt - Celtic Gaul - Norse - Maori - Seraphim from an unspecified religion's Heaven - and Grim Reapers.

It's epic at points, but then I've been tricking readers all along because they end up caring about the people - the Grim Reaper seems to be the favorite.
