"Fast and funny... Mack complements the twisty plot with Eleanor's brisk and biting first-person narration, chock-full of amusing asides (often in footnotes) that examine the movie business and the craft of mystery writing. This one goes down smooth."--Publishers Weekly

"Eleanor continues to be a sarcastic narrator who uses footnotes to speak to the reader. The novel is again full of pop references, romance, and a mix of suspects. It is an easy read that will keep you interested . . . to find out who did it."--Booklist

"A zany, madcap murder mystery to please fans of Catherine Mack's series debut."--Nita Prose, #1 New York Times bestselling author of The Maid and The Mystery Guest

"Eleanor Dash is at it again, breaking the fourth wall with her signature wit and sarcasm in this entertaining whodunit a la Agatha Christie that'll leave you guessing until the very end."--Jeneva Rose, New York Times bestselling author of The Perfect Marriage

"No One Was Supposed to Die at This Wedding was an absolute delight! I whizzed through it in a day . . . A glamorous setting, a smart, witty narrator and a delicious murder plot that picks you up and whisks you along at breakneck speed! More than a masterclass in cozy crime, it's probably the most fun you'll have between the pages of a book!"--Janice Hallett, bestselling author of The Appeal

"A laugh-out-loud page-turner as well as a complex, layered mystery, No One Was Supposed to Die at This Wedding was so much fun! Catherine Mack's books are the perfect vacation read and I'm already looking forward to the next one."--Mia P. Manansala, author of the multi-award-winning Arsenic and Adobo
