The Unraveling of Emlyn DuLaine by Lindsay Franklin

Book 1 of The Rivenlea Sphere

Summary: 

A shattered heart, a fate foretold. The world undone by tales of old.

Emlyn DuLaine just wants to know what happened to her sister, Camille, seven years ago on the fateful day she vanished—literally. Emlyn witnessed Camille unravel and disappear, but no one believes her. Since they think she's crazy, the least the cops could do is solve Camille's case. Is a little closure too much to ask?

But Emlyn's life is upended when she is pulled through a portal into the fantasyland of her childhood imaginings—a magical library holding the storyworlds of every story ever published. And trouble is brewing in the land of Rivenlea. Rogue characters threaten their plot lines, and broken classics are beginning to crumble, but Emlyn only wants to find Camille.

As she searches for her sister, Emlyn begins to learn the reality of Rivenlea and her own origins. A nefarious plot is afoot, and the line between fact and fiction is becoming hopelessly blurred. The truth threatens the storyworlds, Rivenlea, and Earth—the fabric of creation, itself.

Opening Lines:

My sister is dead.

That's the only explanation I can think of, anyway. Why else would I be sitting here, at the police station downtown on a Wednesday afternoon, when I should be doing my calc homework or studying for my physics test? My sister is dead--and they want to question me about it.

Again.
