a fiction book about owls on an island?

Question

I remember reading a fiction book awhile ago, but I'm not sure of the author or title. It was about a girl who winds up on an island(I forget how she got there), but I know there was something like a black hole there or something like a black shadowy figure, and somehow she winds up in this kingdom(I think it was underground) run by human size owls. The king owl had a daughter who was very sick but I think she was supposed to have something major happening in her life soon because she was either a teenager or a baby. I also remember the girl had something with her(I think it was a candy or drink of some sort) that the king owl loved & it made the daughter owl better so the king owl said she could come back anytime she wants as long as she brought whatever it was to eat with her. sorry, i dont remember much, just a girl and a black hole on an island that had a colony of lifesized talking owls with a king and princess owl. If anyone can help it would help a lot. Thanks so much. (:

I just remembered. The thing she had with her that cured the daughter & the king/dad owl loved so much was peppermint candies.

Owl Island by Randy Sue Coburn.

Answer 2

Owl Island: A Novel
by Randy Sue Coburn

From Booklist
Comfortably settled in the idyllic Pacific Northwest enclave of Owl Island, widow Phoebe Allen finally has her life under control. She has a thriving business supplying nets to local fishermen, a lovely adult daughter, a circle of compassionate friends, and a budding romance with a talented local artist. But when her first love, Whitney Traynor, buys a home in town, Phoebe is forced to confront long-stifled secrets from her past. Some 25 years earlier, Phoebe and Whitney, now an independent filmmaker, collaborated on a movie about Kiki de Montparnasse, a real-life doyenne of the Paris demimonde. The work won Whitney critical acclaim, but his unchecked ego and libido lost him the love of his life. Among his moral transgressions: refusing to acknowledge Phoebe's pivotal role in bringing Kiki to the big screen. Coburn's plot shifts haphazardly from present to past and is often painfully predictable (Whitney gets a dramatic dose of karma at novel's end), but her depictions of the Pacific Northwest--with its windswept beaches and cedar-scented air--are evocative and rich
