The Secret Library: A New Keeper by J.C. Gilbert

A bookish girl. A secret library. A thousand portals to a thousand worlds. One choice: face fear, or let it dominate.

For Alex Reed, the world is an awkward place and books are her only escape. But when she is selected by a mysterious library to be its new Keeper she discovers that some books are not for the faint-hearted.

Now Alex must balance her new adventures through the pages with the incomparable obstacles of being an anxiety-riddled teenager. All this might be completely doable, if only Hank would do as he was told.
