THE GIRL WITH GHOST EYES, by M. H. Boroson
When her father must leave town for a few days, her dead husband's best friend comes to visit. Talked into doing an exorcism, Li-Lin finds herself captured in the spirit world, unable to stop an elaborate plot to take over Chinatown. Hampered by her sex, her lack of training, and her powerful father's illness, and a refusal by a powerful monk to help her, she relies on a feisty... wait. No spoilers. For lovers of fantasy, this book is perfect. It's a 4, and I look forward to the next of Li-Lin's adventures.
