My favorite "obscure" fantasy books would probably have to be "The Unlikely Ones." It's about a group of people and animals thrown together through a witch that has cursed all of them. When she dies in a fire, they have to figure out a way to break their various curses. What makes it really unique is that the group consists of a girl stuck in pre-pubescence (maybe around eleven or twelve years old, possibly early teen), a knight, a unicorn that lost its horn,a goldfish, a crow, a kitten, and a toad. Through the magic of their bonding, they learn to talk to each other, although other humans cannot understand the animals. A very odd tale, but very good.
