Who knew my writing was worth so much?

Second hand book dealers in America are offering copies of my Fiends of the Eastern Front omnibus in brand new condition for the pricely sum of $2125.51 [about £1365]. That's more than 100 times the original cover price. However, if you're willing to settle for a used copy, you can pick that up for 94 cents [about 60p].

If that seems less than sane, I offer digital proof of this crazed case of caveat emptor. Assuming you don't want to pay a ludicrous sum for a mint copy of the book, you could always buy the three novels collected within its covers via Amazon's Kindle store. Total cost? About $20. Still leaves you $2100 and change to spend elsewhere...
