In the adaptation of the George R.R. Martin fantasy-book series, Coster-Waldau will play Jaime Lannister, one of the king’s guards and a ruthless usurper of the previous king. The actor, most recently seen in Ron Moore’s Fox pilot “Virtuality,” is repped by WME, Impression and Independent Talent Group.

Another addition is Tamzin Merchant (Showtime’s “The Tudors”), who’ll play Daenerys, an exiled teenage princess.

Also new to the cast: Richard Madden (“Hope Springs”) as Stark’s eldest son, Robb; Iain Glen (“Into the Storm”) as Ser Jorah Mormont, a disgraced knight; Alfie Allen (“The Other Boleyn Girl”) as Theon, Stark’s young ward; Sophie Turner (“Doctor Who”), as Stark’s eldest daughter, Sansa; Maisie Williams as Stark’s young tomboy daughter, Arya.

he’ll make a terrific Jaime.

Dany is very difficult role. She starts out vulnerable and scared, but blooms on the Dothraki sea, and becomes a powerful leader by book’s end. It’s no secret that HBO’s Dany will start out older than Dany does in the book; that was a change that had to be made, if we wanted to keep the sex scenes, and David and Dan and I were all agreed that the sex scenes were essential. Tamzin can play much younger than her actual age (as she does when playing Katheryn) and her sex scenes on THE TUDORS were as hot as anything I’ve ever seen on TV. In her readings, she showed Dany’s other side as well, commanding and charismatic after Drogo’s death. I think she’ll be marvelous.

Imagine a world in which the written word can leave a page to physically lift a man into the air, sharpen his pitchfork, or stop his beating heart.

Such a world is home to Nicodemus Weal, a young wizard with tremendous talent for forging the magical runes which can create spells. Indeed, throughout his adolescence, Nicodemus was thought to be the Halcyon, a powerful magic-user prophesized to save the land from a coming apocalypse known only as the Disjunction.

There was only one problem: runes must be placed in an exact order to create a spell. Any deviation results in a “misspell”–a flawed spell that behaves in an erratic, sometimes lethal, manner. It so happens that Nicodemus is a “cacographer,” one unable to correctly reproduce even simple texts.

Now twenty-three, Nicodemus lives in the devastating aftermath of having failed to live up to prophecy. His magical talent is restricted to the kitchen, where he cleans pots and scrubs walls with childish language. Life slips by one aggravating day at a time until a visiting author identifies an ancient curse infesting the young wizard’s mind. The malicious text has, in fact, stolen his ability to spell. Suddenly, the two wizards closest to Nicodemus are murdered violently and he is forced to flee his home in a desperate quest to recover the stolen part of his mind.

SPELLWRIGHT is the first volume of Nicodemus’ journey across the kingdoms of Faragard, his encounters with monsters and gods who distort language to their own ends, and his internal struggle to accept himself as whole without his ability to spell.
