E-book ethics

 Here's an interesting question – I would not normally consider giving somebody else a copy of an e-book that I have bought. However, what if it is a book that I didn't like? If it were a paper book, I would have no hesitation in passing it on.

In this case, I bought a gay romance – which is reasonably well-written – but when I got well into the plot, it turned out to feature zombies. The zombies were not mentioned in the blurb, and I would not have bought the book if they had been.

Is it therefore ethical to give someone else a copy of my DRM free e-book – assuming that there is anyone out there who actually wants to read a gay romance featuring zombies…
