Allen Strange is having a split personality problem -- literally! After a near-miss with a car, Robbie Stevenson ends up with Allen on the curb...while her brother, Josh, is across the street with Allen's pure alien form. Allen's thrilled. He's a twin. Now Allen can experience life as a real human being while keeping tabs on Alien through their strong mental connection.

Now, Robbie and Josh must figure out how to recombine Allen's two halves...but can they track down Alien before it's too late? Read Less
