Fleabag and the Ring's End by Beth Webb
Another fantastic, rip-roaring adventure of the mangy, three-legged talking cat, Fleabag, and his companions Gemma and Phelan. In this adventure the struggle between good and evil continues. The Porthwain wizards try one last time to take control of the Ring, planning to persuade lady knight Rowanne to join their cause. She has always wanted more power and there is a rumour that a particle of evil blue dust blew into her eyes during the last battle between the Ring Bearer and the Chief Wizard... As ever, the redoubtable Fleabag is never far away. He and a mysterious minstrel called Kern join forces in the quest to find the Ring's End and thus defeat the evil blue magic. But Fleabag has to make one last, great sacrifice to save his beloved mistress Gemma.
