In 2010 I started reading George R. R. Martin's series A Song of Ice and Fire. It's a calque (as T. A. Shippey would say) on the Wars of the Roses, extremely complicated and highly addictive. I read the whole published series and then re-read them again last year in preparation for volume 5. Like many others, the only reason I haven't finished it is because the author hasn't either.
For some people this is a problem. Others write a song about it.
