In this third, and final book of the Ehrich Weisz Chronicles, Ehrich must make good on his promise to his brother Dash that they will return to their home dimension from their current position in the alternate New York, where immigrants are not just from different lands — but from different dimensions. When an attack by the Dimensionals kills passengers and crew of the airship Oriental Clipper, Demon Watch Commissioner Thomas Edison promises to electrocute 54 Dimensional, unless Ehrich and his friends can stop him, while thwarting warlord Ba Tian's planned invasion of New York.

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.

"Metamorphosis is an exciting steampunk adventure whose scientific and ethical lessons arise in ethereal bursts."
— Foreword Reviews

"Metamorphosis includes quite an assortment of villains including one fiend, Ole Lukoje, whose favorite food is human eyeballs. Our heroes prevail in the final battle, and the trilogy comes to a satisfactory conclusion. The tale is particularly current with its description of the treatment by the local inhabitants of the dimensional refugees who are only seeking a better life.
"Metamorphosis is a novel for readers who enjoy complex plots, steampunk settings, and plenty of action. The author makes an effort to provide some background in the early part of the book, but this is one trilogy where it is a definite advantage to read the books in published order to be best able to follow the tale's twists and turns and track the characters who were introduced in the earlier volumes.
