The Left-Handed Booksellers of London by Garth Nix

Susan is searching for the identity of her father and knows London is the place to start. Before truly beginning, she’s drawn into the whirlwind world of the electrifying Merlin (no, not that Merlin) and his strange family of booksellers, who keep the world of goblins and fae in balance. This madcap adventure with unparalleled world building kept me guessing at every step. The Left-Handed Booksellers of London deserves a place on the shelf with Neil Gaiman and Diana Wynne Jones.
