Former KISS guitarist Ace Frehley is opening up with the release of his new book "No Regrets: A Rock N' Roll Memoir."

In his autobiography Ace reveals details from his days with KISS, including the band's formation and rise to fame, the friction within the group, and his departure from the band, as well as his life as a solo artist.  The book is described as Frehley's side of the story, told with "no-holds-barred honesty," "no apologies" and "no regrets."  The rocker penned "No Regrets" with "New York Times" journalist Joe Layden, who previously teamed up with Dave Mustaine for his book, "Mustaine: A Heavy Metal Memoir," and writer John Ostrosky.  While "No Regrets" arrives in stores today, it's already topping two of Amazon.com's best sellers lists.

Frehley will also be hitting the road behind "No Regrets."  He's slate to launch his book tour Thursday with an in-store signing session at the Barnes & Noble in New York on Fifth Avenue.  Additional details on his book tour are available at his website, AceFrehley.com
