What happens in the book?

Ten-year-old Anthony Joplin is excited to finally be old enough to play in the spades tournament, a big deal for every Joplin Man. While his friends worry about school and girls, Ant only cares about living up to his dad’s expectations at the card table. But when his best friend gets grounded, Ant needs a new partner. Shirley, the new girl in class, isn’t who he imagined—she talks a lot of smack and plays tough. Ant’s not sure his dad would like him teaming up with a girl, but Shirley is smart and knows her cards. So Ant teams up with her and keeps it a secret. But soon, he finds out his dad has a huge secret too, one that might tear their family apart.
