The Redemption of Althalus by David Eddings

When Daeva can't win through battle, he tries revolution. First there is a quest to unearth the magical knife that will enable Emmy to assemble her band of essential helpers: Eliar (young soldier), Andine (leader of a small country), Bheid (black-robed priest), Gher (ten-year old orphan), Leitha (telepath/witch).Battles follow against Gelta the Queen of Night and the armies of Daeva involving many devious manoeuvres in and out of the House where Doors can be opened to any place at any time. Emmy is in fact their sister and she's setting out to save the world with Althalus to help her.No easy task. He's read the book written by the god Deiwos, whose evil brother Daeva is trying to unmake the world. Only 2467 years and an ice age later does Althalus re-emerge with the cat, Emmy. What he can't find once he's in the house is the door by which he entered. in the same room as the book Ghend described. Burglar, armed robber and sometime murderer, our hero Althalus is commissioned to steal a book from the House at the End of the World by a mysterious cloaked stranger named Ghend.At the House at the End of the World, he finds a talking cat. But only if Althalus, still a thief at heart, can bring together a ragtag group of men, women, and children with no reason to trust him or each other.A fabulous Eddings standalone fantasy, set in an entirely new magical world.

Her evil brother shares the power, and while Dweia has been teaching Althalus the secrets of The Book, the ancient God has been using the dark magic of his own Book to rewrite history. But Dweia is not the only one able to manipulate time. For when Althalus leaves the House at the End of the World, much wiser but not a day older than when he'd first entered it, thousands of years have gone by. She must be: for in no time at all, she has stolen his heart. She is Dweia, sister to The Gods and a greater thief even than Althalus. On his way to steal The Book from the House at the End of the World, Althalus is confronted by a cat-a cat with eyes like emeralds, the voice of a woman, and the powers of a goddess. Yet of all the men in the world, it is Althalus, unrepentant rogue and scoundrel, who will become the champion of humanity in its desperate struggle against the forces of an ancient god determined to return the universe to nothingness.

He is, as all men know, a thief, a liar, an occasional murderer, an outrageous braggart, and a man devoid of even the slightest hint of honor. It would be sheer folly to try to conceal the true nature of Althalus, for his flaws are the stuff of legend.
