Persistence Of Memory by Laurie Woodward

Saving an art-created world changed little for Bartholomew Borax III. His germaphobe mother still makes him bathe six times a day. He can’t tell anyone about the mystical Artania. And he still must sculpt in secret. But when Bartholomew, alongside skater girl Gwen and fellow artist Alex, are yanked back to the magical world of Artania, they discover that much has changed.

Artanians are being infected with amnesia and no one can find a cure. With epic battles, surreal creatures and a growing threat, the trio race to save Artania from certain doom. But are they already too late?

A magical fantasy adventure for young and old alike, Laurie Woodward's 'Persistence Of Memory' is the fifth book in the Artania Chronicles series.
