Ice Age: Continental Drift: The Junior Novel — Susan Korman

It's just a normal day in pre-history, when suddenly Manny finds himself separated from his family by a huge, gaping hole in the earth! As the continent splits in two, Manny sets off to find the land bridge that will reunite him with his loved ones -- but not without the help of his friends Diego and Sid. Together they sail the high seas in search of home, but before long they run into a rowdy group of pirates. Can the trio navigate the sea, escape the grips of the vicious pirates, and make it back to Manny's family before the gap gets too large?
