Spellbound (The Books of Elsewhere #2) by Jacqueline West
With no way into the house's magical paintings, and its three guardian cats reluctant to help, Olive's friend Morton is still trapped inside Elsewhere. So when Rutherford, the new oddball kid next door, mentions a grimoire Ñ a spellbook Ñ Olive feels a breathless tug of excitement. If she can find the McMartins' spellbook, maybe she can help Morton escape Elsewhere for good. Unless, that is, the book finds Olive first.
The house isn't the only one keeping secrets anymore. Mystery, magic, corruption, and betrayal abound (plus just enough laughs to take the edge off). You'll never guess what happens next in this thrilling, chilling second volume in the critically acclaimed series.
