An author signing and dog pawing take place Friday when Dan Perdios and his golden retriever Morgan head over to Edgartown Books. The duo are here to promote their nonfiction novella, A Golden Retriever & His Two Dads — An Adventure on Cape Cod.

Although the adventure takes place on the other side of the Sound, the Vineyard is known for its goldens. The plot of Mr. Perdios’s book hues very close to his real life, when a golden retriever introduces his dad to a handsome guy, and the men and their dog head off to Cape Cod to make an independent film. Mr. Perdios’s partner James Egan is in fact a movie producer, and has a documentary film in the Martha’s Vineyard African American Film Festival this week. Life&Life, about musician Reggie Austin who tries to redeem his life following a murder conviction 40 years ago, screens on Monday, August 9 at 1 p.m.

The book and paw signing takes place at 2 p.m. on August 6 at Edgartown Books.
