Today....I choose The Bookshelf Muse.
Whether you're just beginning or a seasoned writer, this site is priceless. Six different description thesauruses are listed, at length, in the sidebar of the blog run by Angela Ackerman and Becca Puglisi.
Need a better way to show anticipation?? Hunger?? Stubborness??
Draw a blank on how to describe a bakery?? Bonfire?
Frozen tundra? Frost? Tornadoes? Colors and textures?
There's even a Symbolism Thesaurus for when you are stumped on how to
show a Fall from Grace or a Crossroads or even Superstition.
I live on this site and I highly recommend it to writers everywhere :)
