Max Pendragon is probably the worst squire in King Arthur's kingdom - he'd much rather train to be a wizard instead. So when he accidentally invents a spell that turns people into frogs, it seems his wish might come true. But events take an unexpected turn when Max enters the Novices' Spell-Making Competition and finds himself helping Merlin fight an evil sorceress. There's no way Max's unpredictable frogspell could be of any use. Or is there?

Cauldron Spells brings you more thrills, spills and spells in the second book in the Frogspell series of magical Arthurian adventures. Max Pendragon is not looking forward to attending Morgana Le Fay’s summer Spell School. Not only is his battered cauldron producing slimy sludge instead of perfect spells, but ever since he and his sister Olivia foiled evil Morgana’s plot against King Arthur, they have been wary of her plans for revenge. Max and Olivia soon discover that Spell School has more in store for them than they ever imagined. With the help of Merlin and a mysterious bard, Caradoc, will they be able to outwit Morgana and save Arthur for a second time?

Join Max and Olivia for more magical thrills, spills and spells in their third hilarious adventure. Max and Olivia are loving life in Camelot – not only is Max having magic lessons with the great wizard Merlin, Olivia is finally in training for the Squire’s Challenge. But disaster strikes when Camelot is frozen inside a magical mountain of ice and it’s all Max’s fault! Can he and Olivia rescue Arthur and Merlin from their icy prison before evil Lady Morgana gets to Camelot and seals their doom?

Max and Olivia have discovered that Morgana Le Fay is plotting to use a mysterious 'Swordspell' against King Arthur at the Festival of Chivalry.

But things are made even worse when Merlin is called away unexpectedly, leaving Max and Olivia without his magical protection. With the help of Sir Lancelot, Sir Bertram and Adolphus the dragon, Ferocious the rat and Vortigern the duck, the Pendragon children must quickly uncover Morgana's evil plan, before it is too late for Arthur and Camelot.
