Big Nate Goes for Broke

Big Nate is back in the fourth instalment of his own super-funny series. Big Nate is created by Lincoln Peirce, who inspired Jeff Kinney, author of `Diary of a Wimpy Kid'.
When you've got a head the size of Big Nate's then losing is not an option. But Nate's school P.S. 38 gets beaten by arch-rivals Jefferson Middle School at EVERYTHING. Whether it's sports, maths or a snowball fight in the park, P.S. 38 just can't ever seem to win.
So when their school springs a leak and they have to join forces with Jefferson for a while, Nate and his friends are mortified.
What degrading loses must they face now?
Or can Nate find something that P.S. 38 can actually win at?
