Permanent Rose is the third book in Hilary McKay's laugh-out-loud, award-winning Casson Family series.

It's a long hot, never-ending summer, with no letters for Rose.

Tom went back to America, and Rose hasn't heard from him since. No phone calls, no messages, nothing at all. New friend David, however hard he may be trying, is no replacement.

And home doesn't offer relief either: Dad's left Mum for a young model, Caddy is questioning her imminent wedding and Saffy is trying to find her real father.

Rose is determined to find Tom in New York. But what else will she find on the way?

Follow the family's adventures in the rest of the beloved series: Saffy's Angel, Indigo's Star, Caddy Ever After, Forever Rose and Caddy's World.
