I quite enjoyed 101 Myths of the Bible by Gary Greenberg; an easy read since it doesn't have to be read in order (from myth #1 to myth #101) so if you only have a couple minutes you can skip around to the really short myths. Plus I've loved Egyptian mythology since I was a kid so it was a tactic I used to make the bible interesting to me as I read it.
