Once banished for being zombie-like creatures, the Rainbow-Barfing Unicorns return to their home of Pegasia. Twelve-year-old Xander travels along and discover a world of sugary sweet, fruit-flavoured unicorns - which is a problem, since the Rainbow-Barfing Unicorns are HUNGRY! Plump-full of grotesquely delightful characters and fantastical realms, the adventures of Xander and his team of Rainbow-Barfing Unicorns are so epic they'll make you want to puke.
