Princess Magnolia and Princess Sneezewort are planning a princess playdate, but then a shout from a monster outside Princess Sneezewort's castle interrupts their fun. This is a job for the Princess in Black! Yet when the Princess in Black gets there, she finds only a masked stranger and no monster in sight. Could there be another hero on the horizon? Action and humour abound in this ode to friendship that proves that when shape-shifting monsters intrude on your plans, two heroes are better than one.
