What is your favorite trilogy (series)?
Ack! So many from which to choose!
My current fave is the Charley Davidson series by Darynda Jones. But there's also The Grave Witch series by Kalayna Price and the Chicagoland Vampires by Chloe Neill. And, of course, there's also the Mercy Thompson series by Patricia Briggs.
Right now, I'm on an urban supernatural kick, and those tend to be long-running series books rather than just trilogies. There are some really good dystopian series though, like The Hunger Games, Divergent, Across the Universe, Matched, and more.
