My Invisible Sister — Beatrice Colin; Sara Pinto

Ten-year-old Frank and his family have moved nine times in eleven years, and Frank has had it. This is the last move. No more new schools and new friends. This time he's going to make his sister love the place so much she never wants to leave. Because, you see, when your sister is invisible, she can do pretty much whatever she likes. And if she gets unhappy…

Frank's hilarious mission to keep his family in this particular house seems on track until Frank manages to undo all his good works in one panicked move that he's sure will get them thrown out of town. This first children's novel from two accomplished writers is a charming, totally original sight for sore eyes.
