Astrobia — James C. Paavola

This paranormal, upper middle-grade mystery series follows the adventures of two eighth graders. Sonny and Breanne look nothing alike--a short black boy, a tall white girl. Their special friendship develops when they discover they both have psychic powers: they can read minds, and ghosts communicate with them. Their spirit friends help them solve mysteries and deal with bullies. In Book 3 in the Sonny and Breanne Mystery series, Sonny is contacted by the ghost of a former student who has been abducted by aliens from the planet of Astrobia. It is not long before Sonny and Breanne are both targeted by those same aliens. Sonny is abducted. His return to Earth seems impossible. He must use all of his problem solving skills, and Breanne must focus every bit of her psychic energy to make his return possible.
