Jinx on the Divide is by Elizabeth Kay. The final book in The Divide trilogy. Felix is back in his own dimension and waiting for his friend Betony to come for a visit so he can show her his world. Then Rhino, the class bully, finds Felix's lamp and the brandee within and makes his way across the Divide into the magical dimension where he begins to cause complete havoc. Felix and Betony must find him, stop him, and get him back home, but as usual things don't turn out as planned. An interesting finale to this series, the ending is not what you would expect.
