Ehrich Weisz, Demon Hunter was introduced to steampunk fans in Demon Gate. Now, he is continuing his increasingly desperate quest to rescue his brother in an alternate universe in the sequel, Infinity Coil.

Now a fugitive from Demon Watch, young Ehrich Weisz hides in the underbelly of an alternate New York where immigrants from other dimensions mingle among Americans. Amid growing racial tensions, Ehrich searches for Kifo, the man who stole his brother's mind and locked it inside an ancient medallion. He poses as a stage magician to draw out Kifo's next target—the commissioner of Demon Watch. In the wings, an army awaits Kifo to accomplish his mission so inter-dimensional soldiers can invade New York. Ehrich is willing to risk the outbreak of war to save his brother, but he must decide whether or not he can betray his friends.

Raised in Morinville—a small town north of Edmonton, Alberta—Marty Chan is a playwright, radio writer, television story editor, and young adult author. Marty graduated from the University of Alberta in 1989 with a Bachelor of Arts Degree (English major/drama minor). He fell into improv comedy when he joined Edmonton Theatresports, but his paralyzing stage fright resulted in ”penguin arm“ acting, forcing him to abandon performing and take up writing. His signature play, Mom, Dad, I’m Living With A White Girl, has been produced across Canada, published three times, and broadcast as a radio drama. The stage play won an Elizabeth Sterling Haynes Award for Best New Work and the Adams Chinese Theatre Award at Harvard University. In October 2004, the play had a successful Off Broadway run in New York. Marty was a regular contributor to CBC Radio Edmonton from 1994 to 2000. His weekly commentary series, ”The Dim Sum Diaries,“ recounted his misadventures as the only Chinese kid in a small prairie town. These weekly commentaries were adapted into a half-hour television program (The Orange Seed Myth) which won a Gold Medal for Best Television Pilot at the Charleston World Film and Television Festival, and earned Marty a Gemini nomination for best writing in a children’s program. In 2004, Thistledown Press launched Marty’s first young adult novel, The Mystery of the Frozen Brains, which has become a hit with young readers across Canada. Resource Links magazine rated listed it as one of the Best Books of 2004 for grades 3 to 6. Marty was the first playwright in residence at the Citadel Theatre. He also served as the chair of the Edmonton Arts Council and taught playwriting at the U of A. He received an Arts Achievement Award and a Performance Award from the City of Edmonton. He also earned a Horizon Award from the university for his contributions to theatre. Currently, Marty resides in Edmonton with his wife Michelle and their two cats, Buddy and Max.

"Infinity Coil is well written adventure tale that describes a very unusual version of our world, one complete with multiple villains and heroes, not all of whom are human. For readers who enjoy complex plots, steampunk settings, and plenty of action.
