<p>The tale of an amazing discovery which sets Gavin, his&nbsp;friend Caroline and his enterprising younger brother&nbsp;Thomas on an astonishing quest to find the Wand of&nbsp;Merlin, so it cannot be used to open the interdimensional&nbsp;portal to release the horrible Demogorgon, who will&nbsp;wreak havoc on the world. This tale includes a ferocious&nbsp;animal which roams the countryside by night, an uncouth&nbsp;orphanage director, an imperilled vicar&rsquo;s wife, a secret&nbsp;mini-kingdom in the New Forest, a band of menacing&nbsp;goblins, an army of hideous crones, a man who keeps his&nbsp;mad wife locked in a cage, a next door neighbour with&nbsp;a gun and an attitude problem and the wizard Merlin&nbsp;himself, still alive but not altogether stable.</p>
