Suddenly: Shanghaied! (Suddenly Space Pirates #1)

Nick North hates high school. Awkward and friendless, Nick spends his evenings playing medieval computer games and taking his pet cat to restaurants. When a mysterious, black-sailed pirate ship crash lands next to his apartment building, Nick quickly discovers there are worse things than having no social life. Like getting shanghaied by plucky alien princesses. Or falling in love with quietly troubled first mates.

But hey, what are the odds that Nick's childhood illness is the key to the treasure his new nuisances are avidly looking for? Or that their presence on his planet might literally mean the end of the observable world?
