Sharkland in Bloomington, MN

Max's life in Sharkland is nothing short of amazing-he owns a big house, has the best caretaker ever, and has wonderful friends from school. However, despite all the good things in his life, his gut feeling tells him something dreadful is coming. What could this be? The feeling of dread grows stronger every day.
The same day Max arrives, his friend and caretaker, Jo, and the two sharks she lives with, Mary and Anny, go on a gold hunt. During the epic adventure, Mary and Anny start having the same suspicion. Max does not know why, but it will not be long before he does.
Will Max find the source of this problem, or will the shadow of doom fall over Sharkland before he finds it?
