James's sister is acting like a troll... and now there's a real one in his bedroom.
His little sister Grace has turned into a total troll: grumpy, rude, and completely unreachable. Out of ideas, James turns to the next magical book from his neighbor Stan, hoping for inspiration.
What he gets instead is Tar-a hulking, silent troll who crashes into his room and refuses to leave. Now James is stuck with two trolls: one at home and one that follows him everywhere.
As the lines between reality and story begin to blur, James must tread carefully to uncover the truth behind his sister's mood-and help before both she and Tar are lost to the darkness.
Perfect for fans of Magic Tree House, Dragon Masters, and The Bailey School Kids, this fast-paced, heart-filled adventure brings magic, mischief, and meaning to life.
