Johnathen Livingston Seagull, by Richard Bach. It takes about 20 minutes to read, and when I first read it, it made me sit and stare at the wall for two hours while my mind sailed the wild trade winds.
Of my own work, perhaps a five verse poem I wrote years ago for a story that I haven't finished yet. Mainly because the middle verse came out faster than I could write it down!
It is! My memory is so bad that I usually forget 90% of whatever I read instantly after I finish, but I still remember a whole lot from those three because I love them so much and I've read them so many times. *.* lol
If you like Alice in Wonderland at all or you like general fantasy stuff, even, since it's WAY different than the original Alice stories, it's definitely worth at least trying. It starts with a bang, too, so no worries about a boring beginning to get through. haha
My favorites aren't on Deviant Art, but both are nonfiction. One is about my mom's side of the family, her grandparents. It was an idea sparked by a recent discovery of a family secret on that side of the family that shocked me. Probably something my family wouldn't want me to write, but it was compelling.
Another is a piece I worked very hard on for the past few months that was for a basic composition class. It was on my experiences being overmedicated as a child due to my depression with a lot of really terrible outcomes, but relates it to a larger point about a human tendency of devaluing ourselves and looking for quick-fixes to our problems without truly thinking about how our search for immediate solutions can turn into a long and drawn out nightmare.
In non-fiction, "God is Not Great" by Christopher Hitchens.
In fiction, Ovid's "Metamorphoses."
If you meant my own work, well, I don't really get tired of it. I hold most of my pieces in semi-enmity, and partial adoration. With such polarizing thoughts occupying the (my) mentality, which inheres to the writing, it is hard to get tired of the work.
My current favourite piece would probably have to be a 10-minute stage play that I wrote recently for my Drama Writing class. It was my first attempt at really writing a play and knowing the proper formatting and everything, but I was really pleased with the result in the end. I never posted it to dA, however.
