Life is a puzzle just waiting to be solved - that's how Reya, a young woman with a penchant for solving complex puzzles, sees it.

Reya's life is governed by routine; a roadmap of rules from what foods she eats to what clothes she wears. Most of her time is spent working on her online challenge forum, "The Puzzler". An agoraphobe with obsessive compulsive disorder who hasn’t had sight of the outside world in over six years, Reya views her own symptoms as just another puzzle to be solved.

Now, with the help of her self-made therapeutic entity, Ivan, she has a carefully laid out plan to get her back into society. When their plan goes awry, Reya retreats to the safety of her home. That night, when she sleeps, she finds herself in an unusual place called "the shared Dreamspace". The Dreamspace is a boundless and wonderful place, accessible only to a small selection of individuals from around the world; a place in which one can make anything they desire tangible. Here Reya can finally interact with others, face to face, without needing to leave her home.

As Reya begins to use her talents to help these people and forge new relationships, she starts to feel more and more connected to the Dreamspace. But what is this place? Do these people really exist? Or is the White Room merely an addictive fabrication to retreat from the gravity of her illnesses?
