Good works of Buddhist fiction?

Earlier this year I finished the _Buddha_ series by Osamu Tezuka , and really enjoyed it. I liked the blend of historical references with fictional dramatic elements (and the art, of course). I also read and enjoyed Siddhartha in the past. My question is: Can anyone recommend other similar pieces of Buddhist fiction? Fictional works with Buddhist themes, period fiction with a Buddhist element, or anything similar? (I've been reading so much serious material lately that I'd like to take a break with something a bit more relaxed.) Thanks in advance!
