Xander Stone didn't believe in unicorns—until one puked on him! In this adventure, twelve-year-old Xander first meets the Rainbow-Barfing Unicorns—stinky, zombielike, upchucking creatures from the magical world of Pegasia. They've been banished to Earth for, well, being stinky, zombielike, upchucking creatures. However, Earth presents them with a great HUMANS. Luckily, the dashing, naively heroic Xander vows to protect them and their disgusting secret at all costs.

The secret of the Rainbow-Barfing Unicorns is out and that makes Xander Stone sick! Twelve-year-old Xander is the only person on Earth who knows about the Rainbow-Barfing Unicorns. Except, of course, for a rich and crazy billionaire who will stop at nothing to capture these zombielike, upchucking creatures and get even richer and crazier!

The Rainbow-Barfing Unicorn virus hasn’t infected humans . . . until now! In this adventure, twelve-year-old Xander contracts the mysterious virus of the Rainbow-Barfing Unicorns. The virus gives the unicorns their barfing abilities, but it’s having the opposite effect on Xander—it’s draining him of any color at all! Xander’s fate lies in the hands—er, hooves—of Ronk, the most dimwitted of all Rainbow-Barfing Unicorns. This is not good. In fact, this is bad—really, really bad. Plump-full of grotesquely delightful characters and fantastical realms, Xander and the Rainbow-Barfing Unicorns—from writer Matthew K. Manning (Batman/Teenage Mutant Ninja Turtles Adventures)—is so epic it’ll make you wanna puke.
