What is Mercy Thompson's supernatural ability in Moon Called?

Mercy is a "walker," a rare kind of shapeshifter who can transform into a coyote. She was raised by werewolves after her mother could not care for her, but as a walker she is not a werewolf herself and stands somewhat apart from pack politics.

Is Moon Called the first book in the Mercy Thompson series?

Yes. Moon Called, published by Ace Books in January 2006, is the first novel in Patricia Briggs's Mercy Thompson series, which continued with Blood Bound, Iron Kissed and further sequels.

Is there a graphic novel version of Moon Called?

Yes, but it is a separate, later work: "Patricia Briggs' Mercy Thompson: Moon Called," a comic adaptation written with David Lawrence and illustrated by Amelia Woo, published by Dynamite Entertainment starting in 2011. It is a different catalog entry from this prose novel.

I must admit I'm impressed; I wasn't really sure what to expect from a book about modern werewolves (along with vampires, fae, walkers and other supernatural creatures), but it wasn't much, and I began reading it mostly because of its high rating in Goodreads. In any case, Patricia Briggs managed to capture my attention with her exemplary narration, the almost seamless interaction between the natural and the supernatural world, the great sense of humour, and, of course, with her witty heroine, Mercy Thompson, who, in her own words, her degree in history is one of the reasons she is an auto mechanic (that one made me laughing uncontrollably).
