At first she struggles to adapt to the new lifestyle, but Erin soon starts to come out of her shell, mostly because of her blossoming friendship with the upstairs neighbour, Mr Devilskein, in apartment 6616. Erin, who has an unspeakable secret of her own, discovers that Mr Devilskein is the keeper of six mysterious doors, each leading to six more doors, and so on. He entrusts her with the keys for the Turquoise Door, which leads to an ocean cabinet, the lost works of William Shakespeare and a beautiful Chinese garden, among other things. During her adventures in apartment 6616, Erin befriends a cricket named Zhou and discovers a prisoner named Julius Monk and his Book of Dooms. It's this friendship with the demon Julius that ultimately leads Erin to break her promise to Mr Devilskein and

her soul to save the lives of those she's grown to love.
