I have apparently finished a lot of other people's DNFs, as well as some other books I spent precious days of my life on that I will never get back. These are some I really regret: Entire Sword of Truth series (no further comment needed) Pretty much every Shannara book I've read (no further comment needed) Pretty much everything by Mercedes Lackey I've read (why did it take me so long to realize these were awful, and that she writes the same book over and over again?) Most of the Saga of Recluce (see Mercedes Lackey above) Book of the New Sun (all four of them) Books 2 and 3 of Southern Reach by Jeff Vandermeer (liked the first one a lot; 2 and 3 left me unsatisfied) The Eyes of God series by John Marco (this could've been one good book but instead it was three long books bloated with filler that were in dire need of a good editor) Some series by Sara Douglass that I can't even remember the name of now (ah, Google tells me it was Darkglass Mountain) Chronicles of Narnia (overt and sometimes offensive religious symbolism that I totally didn't get until I reread these in my 20s due to my non-religious upbringing) Belgariad (I might've liked this when I was younger but it was not a good one to pick up in my 30s) I'm unsure whether to put Peter V. Brett's books in this list. As with many of you, I thought the first one was pretty good, but got utterly tired of all the pseudo-Arab stuff in subsequent books, as well as Leesha's behavior. I keep hoping he'll pull out all the stops for the last book, but I kind of doubt it at this point. I find myself not caring any more about the outcome. I read a lot of this before discovering BFB (though the Vandermeer books were this year). I notice a few of mine are on the Worst Fantasy Books list from the main site. Do you all have your own lists like this?
