"I just can't believe that my shy little sister danced the Cha Cha in front of millions of people on Saturday night. I can still remember how mortified you were when I accidentally walked in on you shaking your hips to Shakira when we were teenagers."In the nine years that they've been married, Cate and Kian Warner have been to hell and back but Cate might be facing one of her biggest challenges yet when she's signed up to compete in a dance competition on national TV to raise money for her prenatal depression charity. Still as much of a Neanderthal as ever, Kian doesn't just have to contend with watching another man put his hands all over his "angel", he also has to prepare for what could be his final season as a professional footballer, seeking to end his career on a high by winning the league with his Seattle F.C. team-mates.Of course, it wouldn't be the Warners without a generous sprinkling of family drama. Join them for the cliched emotional rollercoaster as family bonds are pushed to breaking point, friendships are betrayed and old scars threaten to reopen. The question is, when the music stops and the final whistle blows, just who will be the winner and more importantly, will any of them still be speaking to each other?
